Your dashboard, door panels, and bumper trim spend more time in the sun than you do. Yet most of us treat plastic and vinyl like an after-thought—right up until the moment it fades to chalky gray or cracks like old leather. A quality conditioner kit isn’t vanity; it’s preventive maintenance that keeps UV rays, road grime, and repeated wipe-downs from turning expensive trim into an eyesore. Below, we’ll unpack everything you need to know before clicking “add to cart,” so the next time you detail your ride you’re buying science, not snake oil.

3D Leather, Vinyl & Plastic Conditioner | Restores, Conditions & Protects Car Interiors | Non-Greasy UV Protection for Seats, Steering Wheels, & Trim |16 oz
Check Price

Overview: 3D Leather, Vinyl & Plastic Conditioner is a one-step interior spa for every surface that isn’t glass or fabric. Designed for modern car cabins—think coated leather, soft-touch dash vinyl, and textured plastic door cards—the 16 oz bottle revives color and feel without leaving the dreaded “wet look” that attracts dust and fingerprints. A quick wipe-on, buff-off application takes less than ten minutes for an average sedan.

What Makes It Stand Out: The matte, non-greasy finish is the headline here; steering wheels stay grippy, seats never stain light-colored pants, and touchscreens remain smudge-free nearby. Mink oil replaces cheap silicones, so the conditioner actually penetrates rather than floating on top. It’s also one of the few dressings explicitly safe for factory-coated leather, saving you from a costly re-dye job.

Value for Money: At $1.19 per ounce it sits mid-pack, but a nickel-sized dollop covers an entire seat face—expect 25–30 full interior treatments per bottle. That works out to roughly 75 ¢ per detail, far cheaper than specialty leather creams plus separate vinyl protectants.

Strengths and Weaknesses:
Pros: Zero sling on trim, pleasant neutral scent, biodegradable formula, UV blockers that show measurable fade reduction after three months of Florida sun.
Cons: Not for suede/Alcantara, pump sprayer can glob if you’re not careful, matte finish may disappoint fans of high-gloss cockpits.

Bottom Line: If you want “like new” without the slip-n-slide, 3D is the sweet spot between cheap armor-all clones and boutique $40 creams. Buy it, wipe it, forget it—your interior will thank you for years.

Check Price

Overview:
CAR GUYS Plastic Restorer is an 8-ounce, water-based dressing engineered to resurrect faded interior/exterior plastic, rubber, and vinyl without the greasy aftermath common to silicone-heavy gels. Supplied with a contoured foam applicator, the kit targets everything from door panels to bed caps, promising showroom-grade depth that survives rain, soap, and UV for “several months” per coat.

What Makes It Stand Out:
The formula dries fully to a dry-to-touch satin shield—no oily transfer on jeans or detailing towels. Advanced polymer tech beads water on contact, so morning dew or a thunderstorm won’t streak down the flanks. The brand’s US-based mixing, bottling, and live-human customer support add a feel-good, shop-local factor rarely seen in sub-$25 chemicals.

Value for Money:
At $22.49 you’re paying ~$2.80 per ounce, on par with big-box gels yet without the sling, stain, or frequent reapplication. One 8 oz bottle covers an average truck twice; if the claimed 3-5 month longevity holds, annual cost drops below a fancy car-wash ticket.

Strengths and Weaknesses:
Pros: zero greasy residue; rain-proof finish; included applicator saves extra purchases; pleasant citrus scent; made & supported in USA.
Cons: not a permanent dye—deeply chalked trim may need two coats; satin sheen is milder than high-gloss fans crave; premium price vs. gallon-size fleet dressings.

Bottom Line:
For drivers who want a clean, dry, long-lasting revival of trim without sling or towel ruin, CAR GUYS Plastic Restorer is the set-and-forget solution worth the slight premium.


3. 3D Leather, Vinyl & Plastic Conditioner | Restores, Conditions & Protects Car Interiors | Non-Greasy UV Protection for Seats, Steering Wheels, & Trim |1 Gallon

3D Leather, Vinyl & Plastic Conditioner | Restores, Conditions & Protects Car Interiors | Non-Greasy UV Protection for Seats, Steering Wheels, & Trim |1 Gallon
Check Price

Overview: The 3D Leather, Vinyl & Plastic Conditioner is a professional-grade, one-gallon treatment designed to breathe new life into modern car interiors. Whether your seats are leather, vinyl, or coated plastic, this USA-made formula promises a non-greasy, matte restoration that protects against UV damage, cracking, and everyday wear. At $0.33 per fluid ounce, it positions itself as an economical bulk solution for enthusiasts and professional detailers alike.

What Makes It Stand Out: Unlike silicone-heavy dressings that leave a slick, artificial shine, 3D relies on natural mink oil to re-soften surfaces without residue. The multi-surface chemistry is safe for today’s coated leathers yet still nourishes older vinyl dashboards and rubber door seals. VOC-compliant and biodegradable, it’s one of the few gallon-scale products that balances eco-responsibility with professional performance.

Value for Money: A single gallon treats roughly 60–80 average-size vehicles, dropping the per-application cost below a dollar—far cheaper than boutique 16-ounce bottles. For mobile detailers or households with multiple cars, the bulk format eliminates repeat purchases for a year or more.

Strengths and Weaknesses: Pros: non-greasy matte finish; safe on coated leather; UV inhibitors reduce fading; generous coverage; earth-friendly formulation.
Cons: not for suede/Alcantara; matte look may disappoint fans of high-gloss; thin consistency can drip if over-applied; gallon jug needs separate spray bottle for convenience.

Bottom Line: If you want a low-sheen, factory-fresh interior and routinely maintain more than one vehicle, 3D’s gallon conditioner is a cost-effective, eco-conscious staple. Skip it only if you crave glossy pizzazz or own suede surfaces.

STAR BRITE Ultimate Vinyl Guard - Spray on Protection & Shine - Prevent Fading & Cracking - Keep Vinyl, Leather, Plastic & Rubber - 32 OZ (095932)
Check Price

Overview: STAR BRITE Ultimate Vinyl Guard is a marine-grade protective spray designed to restore and shield vinyl, leather, plastic, and rubber surfaces from the harsh effects of sun, salt, and time. Packaged in a generous 32-ounce bottle, this American-made formula promises showroom shine and long-lasting UV defense with minimal elbow-grease—just spray, spread, and wipe.

What Makes It Stand Out: Unlike generic dressings that sit on top, Vinyl Guard’s polymer technology bonds to the substrate, creating a flexible, breathable barrier that repels salt spray, sunscreen, and fish-blood while blocking 99% of UV radiation. The finish is matte-to-satin, never greasy, so boat seats stay cool and non-slip under bare feet. It’s safe for stitching, tinted windows, and even white vinyl—no yellowing or chalky residue.

Value for Money: At roughly 50¢ per ounce, one bottle treats a 25-foot center-console twice over, making it cheaper per application than most 16-oz competitors. Considering it replaces separate cleaners, conditioners, and UV blockers, the cost is easily justified by extended upholstery life and reduced detailing time.

Strengths and Weaknesses: Pros: effortless wipe-on/wipe-off; non-oily finish; pleasant coconut scent; works equally well on RV awning, Jeep fenders, and golf-cart seats.
Cons: not a cleaner—heavy mildew must be removed first; sprayer can drip if nozzle isn’t dialed to mist; satin sheen fades after 4-6 weeks in tropical sun, requiring re-coat.

Bottom Line: If you want one-step UV insurance for vinyl that lives outdoors, STAR BRITE Ultimate Vinyl Guard is the easiest, most economical policy you can buy.


5. CERAKOTE® Ceramic Trim Coat Kit - Quick Plastic Trim Restorer - Ceramic Coating Guaranteed Restoration to Last Over 200 Washes – A Ceramic Coating, Not a Dressing

CERAKOTE® Ceramic Trim Coat Kit - Quick Plastic Trim Restorer - Ceramic Coating Guaranteed Restoration to Last Over 200 Washes – A Ceramic Coating, Not a Dressing
Check Price

Overview:
Cerakote’s Ceramic Trim Coat Kit is a one-step, pre-saturated wipe system that promises to resurrect sun-faded plastic trim and keep it looking showroom-new for 200+ washes. Unlike oily dressings that sling and rinse away, this is a true ceramic coating engineered to bond molecularly with automotive plastics, creating a semi-permanent UV-blocking shell.

What Makes It Stand Out:
The kit ships with two foil-sealed wipes already loaded with Cerakote’s SiO2-rich formula—no bottles, brushes, or masking tape required. The chemistry is the same MIL-spec coating Cerakote applies to firearms, so you’re literally armoring your fender flares. It cures in minutes, leaves a dry-to-touch matte finish, and is safe on textured, smooth, or even vinyl-wrapped trim.

Value for Money:
$16.88 breaks down to roughly eight cents per wash if you hit the advertised 200-wash mark. Comparable trim coatings from professional detailing brands cost twice as much and still require separate prep solvents and applicators. Factor in the time saved and the absence of reapplication every other weekend, and the kit punches well above its price point.

Strengths and Weaknesses:
Pros: truly detergent-proof; zero greasy sling; darkens plastic to OEM hue; single 10-minute job; Made & R&D’d in USA.
Cons: must be applied on perfectly clean, dry trim—any leftover silicone dressing causes fish-eye; foil pouches dry out fast once opened; does not hide deep gouges or chalky oxidation that has already crumbled the surface.

Bottom Line:
If your Jeep’s flares or Honda’s bumper molding have turned chalky gray, Cerakote’s Trim Coat is the easiest, longest-lasting DIY fix south of $20. Follow the prep instructions to the letter and you’ll only need to “trim-dress” once every couple of years.

Check Price

Overview:
BIO-Dimot’s 100 ml Car Plastic Care Agent is a pocket-sized detailing spray aimed at drivers who want a quick, low-effort way to revive faded dashboards, door cards, bumpers, and rubber seals. The water-based formula promises a matte-to-satin finish without the greasy mirror shine associated with cheap dressings.

What Makes It Stand Out:
Unlike many budget trim sprays that rely on heavy silicones, BIO-Dimot uses a gentle, non-fading blend that claims to leave a breathable, anti-static film. The fine-mist trigger gives even coverage with zero drips on vertical panels, and the 100 ml bottle tucks into a glovebox or motorcycle pannier for roadside touch-ups.

Value for Money:
At $15.99 for 3–4 full cars’ worth of applications, the cost per use hovers around $4, undercutting big-brand 300 ml cans that often waste product through wide-nozzle splatter. You’re paying for convenience and a residue-free finish rather than sheer volume.

Strengths and Weaknesses:
Pros: safe on matte plastics, vinyl wraps, and rubber; zero oily sling on paint; light UV inhibitors slow chalking; pleasant citrus scent; tiny bottle ideal for apartments or track-day tool kits.
Cons: 100 ml empties fast on large SUVs; no noticeable beading so protection is short-term (2–3 weeks); sprayer can clog if stored below 40 °F; will not restore heavily oxidized textured bumpers—moderate fading is the limit.

Bottom Line:
BIO-Dimot is a solid maintenance product for enthusiasts who prefer a factory-fresh look over high-gloss glamour. Buy it for swift wipe-on/wipe-off sessions between full details, but pair with a heavier sealant if you need months of UV armor.

Meguiar's Ultimate Black Plastic Restorer, Durable Car Restorer That Gives New Life to Exterior Black Plastic, Vinyl, and Rubber Trim, 12 Oz Bottle
Check Price

Overview: Meguiar’s Ultimate Black Plastic Restorer is a 12-ounce, wipe-on revival serum for faded bumpers, mirror caps, door handles, and rubber moldings. Designed for cars that have seen too many summers, it promises showroom-level depth in minutes without greasy runoff or chalky residue.

What Makes It Stand Out: Unlike thin, silicone-heavy dressings that sling onto paint after the first drive, this water-based gel cross-links to the surface, forming a semi-permanent matte-to-satin film that survives five-plus washes and weeks of rain. The built-in UV blockers slow the oxidation cycle, so you’re not re-applying every weekend. A single dab on a foam applicator spreads far enough to coat an entire bumper, meaning the bottle handles a mid-size SUV three times over.

Value for Money: At $9.44 you’re paying roughly $3 per full-vehicle treatment—cheaper than a single automated car-wash upsell and far less than replacing sun-baked trim. Competitors with similar longevity cost twice as much per ounce.

Strengths and Weaknesses: Strengths: zero sling, no oily fingerprints on jeans, darkens even chalky gray plastic to a factory sheen, and masks light scuffs. Weaknesses: not for textured running boards or interior plastics (can smudge), has a mild solvent scent until fully cured, and over-application leaves a temporary rain-bow on paint that requires quick-detail wipe-off.

Bottom Line: If your ride’s trim looks older than its mileage, Meguiar’s Ultimate Black is the cheapest, fastest facelift you can buy. One ten-minute session buys months of fresh, UV-armor-rich trim—no tools, no mess, no contest.

Captain Don's Graphene-Infused UV Vinyl Protectant, Vinyl Conditioner, & Vinyl Restorer, 32 oz
Check Price

Overview:
Captain Don’s Graphene-Infused UV Vinyl Protectant is a 32-ounce, marine-grade spray that promises to restore, condition, and shield vinyl from sun, salt, and daily abuse. Designed for boat seats, car interiors, and patio furniture, it leans on graphene—an ultra-strong carbon lattice—to create a slick, UV-blocking barrier that repels grime and slows aging.

What Makes It Stand Out:
Graphene is still rare in consumer vinyl care; here it adds measurable slickness and heat dispersion, so surfaces stay cooler and cleaner longer. The single-step spray-and-wipe workflow saves time on large boats or RVs, and the formula contains no greasy silicones that attract dust.

Value for Money:
At $24.99 for 32 oz, the price lands mid-pack against big-box brands, but the graphene boost and months-long durability mean fewer reapplications. One bottle conserves an entire vinyl interior, cutting long-term spend on restorative cleaners or seat replacements.

Strengths and Weaknesses:
Pros: Easy, streak-free application; deep matte-to-satin finish; noticeable UV fade reduction after a full Florida summer; prevents sunscreen transfer on boat seats.
Cons: Light petroleum odor during first hour; overspray can temporarily cloud plastic trim if not wiped; not a permanent fix for already-cracked vinyl—tears remain visible.

Bottom Line:
If you want a one-bottle solution that keeps vinyl supple and UV-safe with minimal elbow grease, Captain Don’s graphene formula earns deck space. It’s an easy, cost-effective shield against costly reupholstery.

Check Price

Overview: Maxshine’s AC09 kit bundles everything you need to resurrect a tired cabin in one grab-and-go box. The 16-ounce AIO Cleaner and Conditioner are pH-neutral, so they play nicely with leather, vinyl, plastic, and cloth alike, while five plush 16”×16” towels and a stiff-but-gentle nylon brush tackle seams, vents, and bolsters without scratching. It’s essentially a mini detail shop in a tote.

What Makes It Stand Out: Unlike one-step sprays that smear grime around, Maxshine splits the job: the cleaner lifts body oils and sunscreen, then the conditioner deposits UV blockers and a satin, non-greeny finish. The included brush is ergonomically knurled—rare at this price—and the 420-gsm towels have edgeless, laser-cut tags that won’t leave new scratches while you remove the old ones.

Value for Money: At $34.99 you’re paying about $7 per component; comparable boutique leather cleaners alone run $15-20. Factor in five premium towels (normally $12-15) and the detailing brush ($8-10), and the chemistry is practically free. Weekend warriors can detail two average sedans before refills, dropping per-car cost below six bucks.

Strengths and Weaknesses: Pros: pH-safe on modern coated leather; zero silicone sling on dash plastics; towels wash up fluffy after dozens of cycles; light citrus scent dissipates quickly.
Cons: Conditioner can bead on hot vinyl—wipe twice; sprayers are basic non-adjustable mist; bottle labels smear when oily.

Bottom Line: If you want professional-grade results without hunting for separate cleaners, conditioners, towels, and brushes, the AC09 kit is the smartest thirty-five dollars you’ll spend this side of a clay bar.

Overview:
Toretark’s 16-ounce interior detailer positions itself as the Swiss-army knife of car care: one bottle claims to clean and protect dashboards, leather, fabric, carpet, plastic, rubber, and even glass while leaving a kid- and pet-safe, matte finish. A dual-action sprayer toggles between clinging foam for set-in grime and wide-angle mist for speedy wipe-downs, and a microfiber towel is tossed in so you can start detailing the minute it arrives.

What Makes It Stand Out:
The 2-in-1 foam/mist switch is genuinely useful—foam stays put on vertical panels so you’re not chasing drips, while mist blankets large upholstery swaths in seconds. The non-toxic, hypoallergenic formula is a rare find at this price tier, and the light green-apple scent beats the chemical stench most economy cleaners leave behind. Finally, the matte, dry-touch finish means no sun-glare on the dash or slick transfer onto clothes.

Value for Money:
At $16.99 ($1.06 per ounce) you’re effectively buying a leather conditioner, fabric shampoo, glass cleaner, and protectant in one—cheaper than grabbing four separate products and far less clutter in the garage.

Strengths and Weaknesses:
Pros: safe for children & pets; versatile on every interior surface; pleasant scent; included towel; leaves non-greasy OEM look.
Cons: Not a heavy-duty stain extractor—deep coffee or ink marks need a dedicated extractor; sprayer feels plasticky and may clog if bottle isn’t rinsed after use.

Bottom Line:
For routine upkeep and light spills, Toretark is the quickest, safest one-bottle solution under twenty bucks. Keep a stronger enzyme cleaner on standby for catastrophes, but make this your weekly go-to for a showroom-fresh cabin.


Automotive plastics are blends of PVC, ABS, polypropylene, and a host of stabilizers. Vinyl seats and door panels are coated with thin layers of PVC and plasticizers that keep them supple. Both materials live inches from a 200-degree firewall and bake under 150-degree greenhouse temps. Ordinary “dressings” can’t replace the plasticizers that out-gas over time, which is why dedicated conditioner kits exist: they restore the chemical balance, not just the shine.

UV Radiation: Public Enemy Number One

Photodegradation begins the day your car rolls off the line. UV-B breaks molecular bonds, UV-A penetrates deeper and attacks the plasticizers that keep vinyl flexible. The result is a two-front war—surface chalking and internal brittleness—making UV inhibitors the single most important feature in any conditioner formula.

The Difference Between Dressing, Sealant, and Conditioner

Dressing equals gloss; sealant equals protection; conditioner equals restoration. A true conditioner kit contains cleaners that open the polymer’s pores, micro-emulsified oils that re-plasticize, and a UV-sealing topcoat that locks the chemistry in place. If any of those three steps are missing, you’re only varnishing the damage.

Water-Based vs. Solvent-Based Formulas

Water-based products play nice with interior vinyl, leave a matte OEM finish, and won’t spot glass. Solvent-based formulas penetrate textured exterior plastic more aggressively and last longer, but they can streak paint if you’re sloppy. Knowing where you plan to use the product dictates which chemistry—and which applicator—is safest.

Matte, Satin, or Gloss: Choosing the Correct Finish

Factory plastic is almost never glossy; vinyl seats even less so. A quality kit lets you layer the topcoat until you hit the desired sheen. If a single wipe produces a wet-mirror look, you’ve bought a show-car dressing, not a conditioner. Look for micro-adjustable finishes or separate “finish control” bottles.

Penetrating Oils vs. Surface Coatings: The Chemistry Battle

Penetrating oils (silicone-free, of course) migrate into the polymer chain and restore flexibility. Surface coatings sit on top and sacrifice themselves to UV rays. The best kits offer both: a thin nutrient layer followed by a breathable sacrificial shell. Skip either step and you’ll be re-applying every wash.

Applicator Types: Foam, Microfiber, or Brushes?

Foam blocks push product into recessed textures; microfiber towels buff away high-spot streaks; soft-bristle brushes agitate grainy plastics like Jeep fenders. A comprehensive kit bundles at least two of these tools—anything less forces you to swipe your paint with the same pad that just soaked up grit from the rocker panel.

How to Read an Ingredient List Like a Detailer

Look for UV absorbers such as benzotriazole or ethylhexyl methoxycinnamate, anti-oxidants like BHT, and plasticizers labeled “dioctyl adipate” or “epoxidized soybean oil.” Red flags are petroleum distillates (they leach OEM plasticizers) and high levels of dimethyl silicone (they attract dust). If the label hides behind “proprietary polymer,” check the SDS sheet online—legitimate brands publish them.

Interior vs. Exterior Application Nuances

Interior vinyl is coated: you want pH-balanced cleaners, low-odor, no overspray. Exterior trim is raw polypropylene: you need stronger surfactants, but you also have to mask adjacent paint. The same kit can do both only if it contains separate dilution ratios or color-coded applicators; otherwise buy two purpose-built formulas.

All-Season Protection: What “Long-Lasting” Really Means

“Up to 12 months” assumes you garage the car, wash it monthly, and live in San Diego. Real-world translation: six to eight weeks on horizontal surfaces, 10–12 weeks on vertical panels. If a kit claims longer, verify it uses a true ceramic-polymer hybrid that cross-links on the surface—anything short of that is marketing.

The Hidden Cost of Silicones and Petroleum Distillates

Cheap kits bulk up on low-grade silicone for instant gloss. Silicone oils oxidize, turn yellow, and embed in pores so future restoration becomes impossible without sanding. Petroleum distillates flash-dry the substrate, accelerating the very cracking you’re trying to prevent. Spending a few extra dollars on silicone-free, water-based chemistry saves hours of correction later.

Storage and Shelf Life: Getting Your Money’s Worth

Heat cycles in your garage can separate emulsions and break UV filters. Store conditioners below 80°F and shake bottles every few months. Unopened, most formulas last three years; once opened, oxygen starts the clock—plan to use interior products within 12 months, exterior sealants within 18.

Pro-Level Prep: Cleaning Before Conditioning

Conditioner can’t jump the soap film. Use an APC (all-purpose cleaner) at 10:1, scrub with a boar-hair brush, then wipe with isopropyl alcohol to remove residual polymers. Only when the towel shows zero color transfer is the substrate ready to accept nutrients. Skipping this step is like waxing over mud.

Common DIY Mistakes That Undo Your Hard Work

Applying in direct sun bakes solvents before penetration. Over-spraying on paint creates greasy rain-runoff streaks that won’t wash off. Cross-contaminating towels spreads dressings to glass—cue wiper smears. Cure each section panel-by-panel, buff with a fresh towel, and change gloves between steps to avoid fingerprint ghosts.

Maintenance Schedules: How Often Should You Re-Apply?

Daily-driver exterior trim: full treatment every season, booster spray every fourth wash. Garage-kept weekend car: bi-annual deep condition, quick detail spray monthly. Interior: light wipe every two months, full nutrient cycle twice a year. Adjust frequency upward if you park outside, live at altitude, or use a caustic touch-free car wash.

Frequently Asked Questions

  1. Can I use the same conditioner on both dashboard vinyl and exterior fender flares?
    Yes—if the formula is water-based and silicone-free; otherwise buy dedicated interior and exterior products to avoid greasy film or UV under-performance.

  2. Will conditioning plastic trim make it attract more dust?
    Only if the formula contains high levels of dimethyl silicone. Modern water-based conditioners with anti-static additives repel dust for weeks.

  3. How long after application can I drive in the rain?
    Wait at least four hours for solvent-based sealants, two hours for water-based. A ceramic-infused coating needs 12 hours of cure for full hydrophobic cross-linking.

  4. Is there any way to restore already-faded gray plastic to factory black?
    Conditioners can darken oxidized trim by 60–80%, but severe UV damage means the polymer chain is fractured. Wet-sand with 800-grit, apply a heavy penetrating oil, then top-coat for best recovery.

  5. Are “ceramic” plastic dressings marketing hype?
    True SiO₂-infused formulas bond to the surface and extend UV protection by 3–4 months. They’re worth the premium on daily drivers, overkill on garaged show cars.

  6. Can I layer a carnauba wax over a plastic conditioner?
    No—waxes don’t adhere to textured plastic and will chalk white within days. Use a dedicated polymer sealant instead.

  7. Why does my windshield fog up after I detail the dash?
    Residual silicone oils volatilize in sunlight and deposit on glass. Switch to a water-based interior conditioner and buff with a clean microfiber until the surface feels dry.

  8. Do I need to wear gloves when applying plastic conditioner?
    Solvent-based formulas can defat skin and carry UV inhibitors that you don’t want absorbed. Nitrile gloves are cheap insurance; water-based products are skin-safe but still messy.

  9. Will conditioner make my trim slippery for future paint touch-ups?
    Quality formulas fully soak in or cross-link, leaving a tack-free surface. If it stays greasy after 24 hours, wipe with an isopropyl-damp towel before touching up paint.

  10. Can I machine-polish plastic trim?
    Soft automotive plastics melt at low temps. Use a non-abrasive chemical restoration first; if polishing is absolutely necessary, opt for a 3-inch foam pad at 1,200 RPM with a dedicated plastic polish and constant temperature checks.
