Nothing ruins the joy of a freshly washed ride faster than noticing a hair-line scratch catching the light. Whether it came from a rogue shopping cart, a careless zip from your jacket, or an enthusiastic puppy greeting you at the driver’s door, light surface scratches are the tiny heartbreaks of car ownership. The good news? You no longer have to book an expensive body shop appointment for every little blemish. Today’s generation of consumer-friendly scratch repair kits can level out clear-coat damage in minutes, saving you hundreds of dollars while restoring that showroom gloss.
But “kit” is a broad term. Walk down any automotive aisle or scroll through online marketplaces and you’ll find everything from single-stage rubbing compounds to multi-step systems that look like miniature chemistry sets. Knowing which formula, tool, or accessory actually matches your paint—and your comfort level—can make the difference between an invisible fix and a foggy patch that screams amateur hour. This guide breaks down the science, shopping criteria, and pro-level tips you need to confidently choose a scratch repair solution for light clear-coat damage, all without pushing you toward one specific brand.
Top 10 Car Scratch Repair Kit
Detailed Product Reviews
1. Meguiar’s Quik Scratch Eraser Kit, Car Scratch Remover for Repairing Surface Blemishes, Car Care Kit with ScratchX, Drill-Mounted Pad, and Microfiber Towel, 4 Count
Overview:
Meguiar’s Quik Scratch Eraser Kit turns the drill you already own into a miniature body-shop, promising to buff away light blemishes without elbow grease. The 4-piece box pairs the brand’s widely trusted ScratchX formula with a foam pad that threads onto any standard drill, plus a plush microfiber for final wipe-down. Designed strictly for surface-level defects—think keyed-door hairlines, parking-lot scuffs and paint transfer from another bumper—the kit aims to deliver pro-looking results in under ten minutes per panel.
What Makes It Stand Out:
Leveraging drill power instead of hand pressure means consistent speed and even heat, the two variables detailers charge for. ScratchX’s micro-abrasive chemistry cuts only damaged clear-coat, leaving healthy paint untouched; the included pad’s density matches the compound perfectly, eliminating the guesswork of aftermarket accessory pairings. Clear-coat-safe certification and explicit “no haze” claim give first-timers confidence to attack blemishes instead of ignoring them.
Value for Money:
At $18.19 you’re effectively buying a single bottle of ScratchX (normally ~$10) and getting the drill pad, a quality microfiber and the guided procedure gratis—far cheaper than a $75-$150 professional buffing session. One kit handles a sedan’s worth of light scratches; pad and towel rinse for reuse on future nicks.
Strengths and Weaknesses:
- Works only on CLEAR-CAT scratches; won’t help deep gouge or primer reveal
- Drill requirement may exclude apartment dwellers or cordless-only owners
- Foam pad clogs quickly—frequent rinsing prevents micro-marring
- Results diminish on single-stage or matte finishes
Bottom Line:
For shallow, clear-coat level eyesores, Meguiar’s Quik Scratch Eraser Kit is the fastest, cheapest confidence-builder you can buy. Keep expectations realistic, follow the three-step process, and your daily driver will shine like it just left the detail bay—without leaving your driveway.
2. Carfidant Scratch Repair and Swirl Remover - Car Paint Scratch Remover & Restorer Kit with Buffer Pad - Polishing & Waxing Kits - Compound for Vehicles Paint Repair - 8.4 fl. Oz.
Overview:
Carfidant’s Scratch Repair & Swirl Remover is a one-bottle, one-pad solution for drivers who want showroom gloss without a detailer’s bill. The 8.4 oz kit pairs a diminishing-abrasive compound with a 3-inch foam applicator, letting you hand-polish isolated blemishes in minutes instead of masking them with touch-up pens.
What Makes It Stand Out:
Unlike most budget removers that rely on heavy fillers, Carfidant uses alumina-based micro-abrasives that level the clear-coat rather than hide it. The formula is silicone-free, body-shop safe, and genuinely effective on light clear-coat scratches, oxidation and water spots—rare versatility at this price.
Value for Money:
At $21.97 you’re paying less than a single professional buffing hour and getting enough product for at least a dozen door-panel corrections. The included pad alone saves a $5–$8 purchase, making the kit a genuine bargain for lease returns or pre-sale spruce-ups.
Strengths and Weaknesses:
Pros: works quickly by hand, safe on all factory paints, pleasant chemical smell, and restores gloss without additional wax.
Cons: will not eliminate deep primer-level scratches, pad is small for large panels, and thin formula can sling if over-applied. Expect 60-70 % improvement on medium swirls, not 100 % disappearance.
Bottom Line:
For light clear-coat love marks, Carfidant delivers pro-grade results with driveway convenience. Keep expectations realistic—deep gouges still need paint—and you’ll be thrilled with the mirror-like finish this $22 kit returns.
3. Quick Scratch Remover for Cars, 2025 Upgraded Scratch Remover for Vehicles, Car Paint Scratch Repair Kit, Car Scratch Repair with Sponge for Deep Scratches
Overview:
The 2025 Quick Scratch Remover is a budget-friendly, all-in-one kit that promises to buff away light paint blemishes without a trip to the body shop. A 100 ml squeeze bottle of mild abrasive paste pairs with a contoured sponge, giving DIYers everything they need for glove-box touch-ups. The palm-sized package slips easily into a door pocket, ready for parking-lot emergencies on cars, bikes, or scooters.
What Makes It Stand Out:
No extra tools, compounds, or electrical buffers are required—clean, dab, wipe, shine. The upgraded micro-abrasive formula is color-agnostic, so one SKU works on any factory clear coat, metallic, or solid finish. The sponge’s dual-texture sides let you start gently and ramp up cutting power only where needed, minimizing the risk of “burning” thin clear coats.
Value for Money:
At $18.99, the kit costs less than most single-use dealership touch-up pens and replaces an arsenal of polishes. If it saves one professional buffing session ($80-$150), it pays for itself five times over.
Strengths and Weaknesses:
Pros: pocket-size portability, beginner-proof three-step process, pleasant citrus scent, works on headlights and motorcycle fairings too.
Cons: will not fill or hide deep scratches that catch a fingernail; not effective on exposed primer or plastic trim; paste can dry out if the cap isn’t tightened fully.
Bottom Line:
Keep one in every vehicle for the inevitable grocery-cart kiss or branch swipe. It’s not magic, but for superficial scuffs, this $19 kit delivers showroom gloss in five minutes—no appointment necessary.
4. Meguiar’s Ultimate Compound - Pro-Grade Car Scratch Remover, Paint Correction Compound That Removes Defects While Adding Gloss and Shine, Single Stage and Clear Coat Scratch Remove, 15.2 Oz
Overview:
Meguiar’s Ultimate Compound is a 15.2 oz pro-grade liquid abrasive engineered to erase moderate to heavy clear-coat defects in one DIY-friendly step. Designed for hand or dual-action application, it replaces multi-stage compounding for weekend detailers who want body-shop results without body-shop prices.
What Makes It Stand Out:
The bottle packs Meguiar’s exclusive micro-abrasive technology: diminishing particles that cut fast then refine themselves, eliminating the customary follow-up polish. Clear-coat-safe chemistry means no fillers, no silicone haze, and no week-long cure wait—just wipe, buff, and move straight to wax or ceramic coating.
Value for Money:
At $13.16 ($0.87/fl oz) you get 3-4 full sedan corrections per bottle, equaling roughly $3 per car—far cheaper than $150+ pro detail or even a single-stage polish pad. A penny-dime-sized drop goes a long way, so the cost per defect removed is almost laughable.
Strengths and Weaknesses:
Pros: lightning cut on swirls, water spots, and 2000-grit sand marks; works equally well by hand or DA; zero dust; pleasant tropical scent; clear-coat & single-stage safe.
Cons: not ideal for deep primer-level gouges; can matte plastic trim if you wander; short open-time in direct sun—work panel-by-panel.
Bottom Line:
If your paint feels like a roadmap of wash scratches and oxidation, Meguiar’s Ultimate Compound is the fastest, cheapest ticket back to glossy. Keep expectations realistic on rock chips and tape off trim, and this $13 bottle will out-perform compounds costing three times as much.
5. PIMAG Upgraded Car Scratch Remover Kit, Scratch Remover for Vehicles ＆ Cars, Car Paint Scratch Repair, Polishing ＆ Rubbing Compound Paint Restorer with Applicator Pad, add Gloss ＆ Shine 8.4OZ
Overview:
PIMAG’s Upgraded Car Scratch Remover Kit promises pro-level results for driveway detailers. The 8.4 oz squeeze bottle arrives with a contoured foam applicator pad and claims to erase light-to-medium blemishes—door-ding scuffs, shopping-cart kisses, branch whips—in under twenty minutes, no power tools required.
What Makes It Stand Out:
The formula doubles as a mild polish; diminishing abrasives level the clear-coat while synthetic sealants cure to a UV- and rain-repellent film, so you’re correcting and protecting in one swipe. The neutral-pigment paste bonds to metal, plastic, and painted fiberglass alike, letting you tidy bumper caps and mirror housings without color-matching anxiety.
Value for Money:
At $19.99 you’re paying roughly the cost of a single espresso per scratch—far cheaper than a body-shop quote or touch-up pen that never quite blends. A full bottle covers 40–50 typical nicks, dropping the per-repair price below fifty cents.
Strengths and Weaknesses:
Pros: truly beginner-friendly, no masking or sanding; leaves a glossy, wax-like finish; water-beading lasts 6–8 weeks.
Cons: won’t fill deep primer-level gouges; dark metallic paints may show faint haze if residue isn’t buffed thoroughly; applicator pad is single-use—microfiber towels work better for final polish.
Bottom Line:
For swirl marks and superficial scars, PIMAG delivers near-instant gratification without a professional price tag. Keep it in the glove-box for quick clean-ups after road trips; just don’t expect it to re-spray your fender.
6. Carfidant Scratch and Swirl Remover - Car Scratch Remover for Vehicles Paint - Polishing Compound for Cars with Pad and Towel - Cutting and Buffing Compound for Paint Restorer
Overview:
Carfidant’s Scratch & Swirl Remover is a 3-in-1 polish, compound, and gloss enhancer marketed to weekend detailers who want pro-level results without a machine polisher. The 8-oz bottle ships with a 3-inch foam applicator and a microfiber towel—everything you need for a single-panel touch-up or a full hood revival on any OEM paint, clear-coated or single-stage.
What Makes It Stand Out:
The formula is body-shop safe: no silicone, no fillers, no perfume, so you can spot-treat a fender today and ceramic-coat tomorrow without fish-eye drama. The diminishing abrasives break down as you hand-buff, meaning one product both cuts and finishes instead of the traditional two-step compound-plus-polish dance.
Value for Money:
At $26.97 you’re paying roughly $3.25 per ounce—cheaper than a single-serve Starbucks and far less than a professional paint correction that starts at $150. Throw in the pad and towel and the kit effectively costs under twenty bucks if you already own microfibers.
Strengths and Weaknesses:
Pros:
- Works by hand in 5-10 min per panel; no tools required
- Removes light swirl marks, water spots, and oxidation
- Safe on all colors, including tri-coat reds and matte wraps
Cons:
- Will not level deeper scratches that catch a fingernail
- Bottle cap tends to leak if stored sideways
- Towel lint can mar very soft black paints unless swapped for a premium cloth
Bottom Line:
For 90 % of daily drivers peppered with car-wash swirls and grocery-cart scuffs, Carfidant delivers “just-detailed” gloss in under an hour. Keep expectations realistic on deep gouges, but for everything else this is the easiest, cheapest paint pick-me-up you can buy without plugging anything in.
7. FAVIRZCE Car Scratch & Swirl Remover Kit: 500ml Automotive Scratch Eraser Restorer & Polishing with Buffer Pad - Scratch Eraser Kit for Light Scratches Oxidation & Water Spots (500ML)
Overview:
FAVIRZCE’s 500 ml Car Scratch & Swirl Remover Kit promises pro-level paint correction without the pro-level bill. Packed with one generous bottle of micro-abrasive compound and a contoured foam hand pad, the set targets light scratches, oxidation, water spots, and swirl marks on everything from motorcycles to boats.
What Makes It Stand Out:
The formula is tuned for “hand-only” use—no rotary buffer required—so first-timers can work small sections on a weekend and still see a crisp, glossy reflection. The compound is body-shop safe on clear-coat, single-stage, and multi-stage finishes, and the 500 ml supply is roughly double what budget kits offer.
Value for Money:
At $20.99 you’re paying about what a single scratch-pen costs, yet you receive enough product to polish an entire sedan twice. Skip one $150 detailing appointment and the kit has already paid for itself.
Strengths and Weaknesses:
Pros
- Works quickly by hand—no tools, no cords
- Large 500 ml bottle handles multiple vehicles
- Safe for every factory paint color and type
- Pleasing citrus scent and low-dust formula
Cons
- Won’t level deep scratches that catch a fingernail
- Foam pad supplied is basic; pros will want microfiber or a DA machine for severe swirls
- Requires elbow grease on heavily oxidized panels
Bottom Line:
For $21, FAVIRZCE delivers an easy, low-risk intro to paint correction. Keep expectations realistic—light blemishes disappear, deeper gouges need filler—but if you want showroom pop without the showroom invoice, this kit belongs in your garage.
8. Car Scratch Remover, Car Paint Scratch Repair, Touch Up Paint for Cars Deep Scratch Repair Kit for Branch Scratches Nail Scratches Swirl (12, Silver Gray + Titanium Gray)
Overview:
This 14-piece Silver Gray + Titanium Gray kit promises pro-level touch-ups for everything from fingernail swirls to branch-induced gouges without a trip to the body shop. At $11.99 you get two color-matched paint pens, primer filler, swirl remover, mini sanders, masks, gloves and polishing bits—enough hardware to tackle three-step repairs on cars, bikes or patio furniture.
What Makes It Stand Out:
The dual-tone paint pens (two slightly different grays) let you feather and blend until the scratch literally disappears on metallic factory finishes; most budget kits offer only one flat hue. The included antioxidant “brightness” sealant doubles as a UV-shielding top-coat, a step competitors usually skip. Finally, the 0.6 fl. oz. pens store like Sharpies—no dried-out blobs next year.
Value for Money:
Comparable dealership pens cost $15-20 each and still need clear-coat. Here you get two pens plus all prep/polish consumables for the price of a fast-food meal. Even if you use half the kit on one ugly door scuff, you’ve saved at least $100 in shop labor.
Strengths and Weaknesses:
- Color-blending system actually works on metallic silver/gray
- Everything included—no surprise hardware-store runs
- Pens start flowing quickly and don’t glob if you follow the “shake 10 s” rule
– 0.6 oz won’t cover large bumper scuffs; deep gouges still need patience (3-4 micro-layers)
– Masking tape supplied is narrow; buy wider tape for big panels
– Dry-time is 10-15 min between coats; rushed jobs look worse than the scratch
Bottom Line:
For light-to-moderate scratches on silver or gray metallic paint, this is the best under-twelve-dollar insurance policy you’ll find. Practice on cardboard, layer thinly and the repair becomes invisible—saving a costly repaint. Heavy collision damage still belongs to the pros, but everyday parking-lot battle scars disappear with this kit.
9. Nano Sparkle Cloth Car Scratch Remover Paste for Vehicles, 2025 Upgrade Car Scratch Repair Kit to Erase Car Paint Scratches, Water Spots
Overview:
The 2025-upgrade Nano Sparkle Cloth kit is a budget-friendly, DIY answer to the tiny blemishes that make a daily driver look tired. You get two syringes of mild polishing paste and five reusable nano-fiber cloths impregnated with micro-abrasives and sealant polymers—no machines, no masking, just hand buffing.
What Makes It Stand Out:
Unlike traditional compounds that can burn through clear coat, the formula uses “nano” alumina spheres that break down as you rub, becoming progressively finer. The cloths leave behind a thin acrylic coating, so the repaired spot matches the surrounding gloss and gains a few weeks of water-beading protection in one step.
Value for Money:
At $14.99 you’re paying about $3 per cloth; even if you throw the extras in the glove-box for door-ding emergencies, the kit still costs less than a single professional touch-up pen. For lease returns or sale-day spruce-ups, it’s cheaper than a car-wash deluxe package.
Strengths and Weaknesses:
Pros: genuinely erases light swirl marks and water spots in under five minutes, works on glass and plastic trim as advertised, no greasy silicone film, reusable cloths rinse clean for 10–12 uses.
Cons: will not fill deeper scratches that catch a fingernail; dark colors can reveal faint haze if you skip the final wipe; paste tube seals poorly—store upright or it dries out.
Bottom Line:
Keep your expectations microscopic and this kit over-delivers. It’s a glove-box essential for maintaining a just-washed shine between details, but anything deeper still demands body-shop attention.
10. 3M Scratch Removal System, 39071, 1 Kit
Overview:
The 3M Scratch Removal System 39071 is a pocket-sized body-shop-in-a-box designed for drivers who cringe at every parking-lot scar. The kit contains three color-coded 3000-grit sanding discs, a purple compounding pad, a black polishing pad, plus 1-oz tubes of 3M rubbing compound and scratch remover—everything you need to erase light clear-coat mars without paying a detailer.
What Makes It Stand Out:
3M’s 3-step “sand-compound-polish” sequence is the same protocol professional painters use on $100k rides, yet the kit ships with a drill-mount adapter so anyone can mirror that process in 20 minutes. The abrasives are engineered to break down gradually, preventing the dreaded “burn-through” that cheaper pens often cause.
Value for Money:
At $23.90 you’re buying one lunch’s worth of peace of mind; a single body-shop quote starts at $150. Consumables are generous enough for 6–8 fingernail-length scratches, dropping the cost below $4 per repair—cheaper than most touch-up sticks that merely hide damage.
Strengths and Weaknesses:
Pros: Fool-proof color-coded steps; drill adapter saves elbow grease; restores gloss indistinguishable from factory finish.
Cons: Not for deep primer-level gouges; black paint may show micro-marring if final polish is rushed; single-use sanding discs mean you’ll reorder refills.
Bottom Line:
If your blemish is shallow enough to catch a fingernail but not draw blood, this kit is the cheapest insurance against depreciation and embarrassment. Keep one in the glove-box; your future self (and resale value) will thank you.
Understanding Modern Car Paint Layers
Before you open any tube or bottle, it helps to visualize what you’re working on. Today’s factory finishes are a layered cake: bare metal, primer, base-coat color, and finally a clear urethane that provides UV protection and gloss. Light scratches—those you can’t catch with a fingernail—typically sit in the clear coat only. Repair kits rely on micro-abrasion, chemical filling, or a combination of both to level that top layer so light reflects evenly again.
Why Light Scratches Are Easier to Fix Than Deep Ones
Depth dictates difficulty. Because clear coat is the uppermost and thickest paint layer (usually 1.5–2 mils), you can safely remove a microscopic amount without compromising UV protection or color. Once a scratch penetrates into color or primer, you’re into repaint territory. Recognizing that boundary—and choosing a product engineered for it—prevents over-sanding and costly resprays.
Key Components Found in Most DIY Kits
Scratch repair kits aren’t magic markers. They’re miniature systems that combine cleaners, abrasives, fillers, and protectants. Typical box contents may include a pre-treatment degreaser, diminishing-abrasive compound, microfiber cloths, foam or wool applicators, and a finishing sealant or wax. Premium kits add color-matched paint pens, blending solutions, curing sprays, and even handheld polishing tools.
Abrasive vs. Filling Technologies Explained
Products fall into two camps: those that cut (abrasives) and those that mask (fillers). Abrasive compounds use engineered micro-particles that break down into smaller sizes as you rub, gradually flattening the scratch edges. Filling products rely with polymers or waxes that settle into the groove and temporarily hide it. Some kits hybridize both approaches, polishing first then sealing with a filler for added gloss.
Matching the Kit to Your Paint Type and Color
Metallic, pearl, solid, matte—each finish reflects light differently. Highly metallic paints can reveal burnishing if you over-polish, while matte finishes reject gloss altogether. Ensure the kit is safe for clear-coated finishes and, if it includes tint, that the pigment blends with your color code (found on the door jamb sticker). Many manufacturers offer color charts; cross-check before ordering.
Essential Features to Look For
- Diminishing abrasives that self-refine to prevent hazing
- UV-stable sealants to protect freshly leveled clear coat
- Lint-free, edgeless cloths to avoid new scratches during buffing
- Non-silicone formulas so body shops can still repaint if needed
- Chemical-resistant gloves—your skin will thank you
Safety Considerations Before You Start
Work in a shaded, dust-free area above 60 °F (15 °C). Cold paint hardens abrasives; hot panels evaporate solvents too fast. Mask off adjacent plastic trim to avoid chalky white residue. Wear nitrile gloves and eye protection—many compounds contain alumina or kaolin that can irritate skin and lungs. Finally, have a garden hose or spray bottle handy to flush away run-off; some compounds stain concrete.
Step-by-Step Application Techniques
- Wash and clay the panel to remove surface grit.
- Tape a border around the scratch to monitor progress.
- Prime your applicator with a pea-sized amount of compound.
- Work at low speed (hand or machine) using cross-hatch passes—horizontal, then vertical.
- Wipe with a clean microfiber, inspect under LED, and repeat if the scratch is still visible.
- Finish with a sealant or wax to lock in the gloss.
Common Beginner Mistakes to Avoid
- Over-application: more compound ≠ faster results; it just clogs pads.
- Dry buffing: skipping lubrication generates heat and haze.
- Circular scrubbing: random motions create swirl holograms.
- Skipping sealant: exposed clear coat oxidizes quickly, bringing the scratch back.
How to Test Scratch Depth Before Buying Anything
Drag a fingernail perpendicular across the mark. If it catches, you’ve likely breached the clear coat. No catch? You’re probably in DIY territory. For borderline cases, spritz water; if the scratch disappears temporarily, it’s shallow enough for a consumer kit.
Eco-Friendly Formulations and Low-VOC Choices
California and EU regulations have pushed manufacturers toward water-based solvents and biodegradable abrasives. Look for “low VOC,” “prop 65 compliant,” or “water-borne” labels. These formulas reduce indoor fumes and are safer for planet and passenger.
Price vs. Performance: Budgeting Wisely
Entry-level kits ($10–$20) rely on basic fillers—great for last-minute show prep but short-lived. Mid-range ($25–$45) add quality abrasives and UV sealants, ideal for annual maintenance. Premium systems ($50–$100) bundle polishes, pads, and sometimes mini tools that rival professional results. Evaluate how often you detail; occasional users can stay mid-range, while enthusiasts benefit from the versatility of top-tier kits.
Storage and Shelf Life Tips
Heat is the enemy. Store bottles upright in a climate-controlled space; garages that swing from 30 °F to 100 °F will separate polymers and shorten shelf life to six months. Tightly seal caps to prevent solvent evaporation. Microfiber pads should live in sealed bags so they don’t attract garage dust that could re-scratch paint next time.
When to Call a Professional Instead
If the scratch is through the color, on a plastic bumper with no clear coat, or adjacent to sensitive ADAS sensors, let a technician handle it. Likewise, exotic finishes like frozen matte or tri-coat pearls often require factory tint and spray techniques that exceed driveway capability.
Maintaining Your Paint After a Successful Repair
Avoid automated car washes for at least two weeks; high-pH soaps can strip fresh sealant. Apply a spray sealant every 3–4 months to maintain UV protection. Consider paint-protection film on high-impact areas (door edges, trunk lid) to prevent repeat scratches. Regular gentle washing with a pH-balanced shampoo remains the cheapest insurance against future swirls.
Frequently Asked Questions
-
Will a scratch repair kit remove scratches completely or just hide them?
If the scratch is limited to the clear coat, a quality kit can level the surface so the flaw becomes optically invisible; it’s not “hidden” but physically removed. -
Can I use the same kit on my plastic headlights or motorcycle windshield?
Most clear-coat compounds are safe on acrylic headlights, but always test on a corner first; some contain solvents that craze polycarbonate motorcycle screens. -
How long does a typical DIY repair last?
When finished with a UV-stable sealant, results can last 12–24 months. Skipping the sealant may drop longevity to a few months. -
Is it normal to see haze right after polishing?
Yes, micro-marring is common. Wipe with an alcohol-based panel wipe, then apply finishing polish or sealant; haze should disappear. -
Do I need a machine polisher, or can I do everything by hand?
Hand application works for isolated, light scratches. Machines speed up the process and yield more uniform results on larger panels. -
Will repairing a scratch affect my car’s resale value?
A seamless DIY repair maintains value better than an obvious scratch; just document the work so buyers know it wasn’t body filler hiding rust. -
Can I apply ceramic coating immediately afterward?
Wait 12–24 hours after the final sealant to ensure all solvents out-gas; otherwise the coating may not bond properly. -
What’s the difference between a rubbing compound and a scratch remover?
Rubbing compounds are more aggressive, designed for heavy oxidation. Scratch removers use finer abrasives and fillers tailored for light clear-coat marring. -
Are these kits safe for ceramic-coated cars?
Abrasives will partially remove the coating. Use a filler-only product, or re-coat the panel after repair. -
Why does my scratch reappear after a few washes?
You likely used a filler-heavy product without sealing. Road grime strips fillers; repeat the process and finish with a durable sealant or wax.
