Prices may varyThe manufacturer's Safety Data Sheet classifies this product with one or more GHS Category 1 health hazards — the most severe tier. The hazard statements in quotes below are the verbatim GHS language from the SDS, as required by OSHA's Hazard Communication Standard. The line under each statement translates the GHS classification into plain language.
GHS Category 1 germ-cell mutagenicity — classified as suspected of causing heritable genetic damage.
GHS Category 1 carcinogenicity — classified as suspected of causing cancer with repeated or prolonged exposure.
If swallowed, inhaled, or splashed in eyes:
Call Poison Control immediately at 1-800-222-1222 (US, 24/7, free) and have the product container with you. Poison Control's standing guidance is to not induce vomiting after chemical exposure; they will direct first-aid steps based on the specific product.
About this product's hazards. This product's Safety Data Sheet uses signal word danger. Read the manufacturer's SDS and follow all safety instructions before use. CarCareTruth ratings translate the manufacturer's safety sheet. They do not replace the SDS or substitute for a hazard assessment specific to your task.
Health score is for adult use as intended, per the manufacturer's SDS. It does not model child ingestion, accidental spill cleanup, or off-label use. See the safety panel below for full hazard classification, and /disclaimer for the full editorial scope.

TL;DR Stops squeaky door seals and binding weatherstripping; community confirms 1-2 months between treatments. No straw included, so tight-space application risks silicone overspray on adjacent paint. The propellant carries germ-cell mutagenicity and carcinogenicity classifications. Wear nitrile gloves and safety goggles, use outdoors or with a car door open. DANGER signal word is real.
Permatex 80070 lubricates door seals, window tracks, rubber weatherstripping, and bushings; stops squeaking and binding without attracting dust. The wide-fan nozzle sprays foam, not a fine mist, and no precision straw is included. Community confirms it kills squeaks on first application and holds 1-2 months on outdoor door seals. Keep it off painted panels and any surface that may need bodywork; silicone residue prevents primer and paint from sticking.
Car owners dealing with squeaky door seals, sticking window tracks, or binding weatherstripping. Skip it for metal-on-metal surfaces including load-bearing hinges, fasteners, and chains; white lithium grease is the right tool there. Never apply silicone spray to brake components.
DANGER signal word: the propellant carries germ-cell mutagenicity (Category 1B) and carcinogenicity (Category 1A) at mixture level, plus California Prop 65. SDS §8 specifies nitrile gloves and safety goggles; a NIOSH organic vapor respirator when ventilation is inadequate. Use outdoors; propellant is extremely flammable. Environment score 6: estimated 245 g/L propellant VOC applies a deduction offset by the leave-on pathway multiplier.
The petrolatum carrier in this product is rubber-friendlier than petroleum-naphtha-based aerosols, and owners report no EPDM or neoprene degradation in the review corpus. The aerosol propellant vaporizes on release, so what stays on the seal is primarily petrolatum and silicone active. That said, the SDS does not list this product as a pure silicone-oil formula, so it carries a slightly lower surface-safety rating than products with confirmed silicone-only chemistry. For most door seal and weatherstripping applications, owners report good compatibility.
The aerosol propellant (30-60% C3-C4 hydrocarbons, a propane/butane blend) carries germ-cell mutagenicity (Category 1B) and carcinogenicity (Category 1A) classifications under GHS at mixture concentrations. These are the codes that escalate the signal word to DANGER. The propellant fraction is unusually high for a consumer aerosol, which is why the health profile is more serious than a typical silicone spray. Use outdoors or with a car door open, wear nitrile gloves and safety goggles, and keep the can away from ignition sources.
Community reviews confirm roughly 1-2 months of protection on outdoor-exposed door seals and rubber weatherstripping under normal driving conditions. This is typical commodity durability for an aerosol silicone spray. High-cycle surfaces like daily-driver door seals may need reapplication toward the lower end of that range; trunk seals and window tracks used less frequently tend to hold longer. The product label says 'long-lasting' without specifying a duration; community data is the more reliable guide.
Silicone spray is not a metal-on-metal lubricant. For hinges under mechanical load, fasteners, or any metal contact that generates friction, white lithium grease or a multi-purpose oil is the right tool. Silicone spray is for rubber seals, weatherstripping, plastic trim slides, and window tracks. Also, keep it entirely away from brake components; any silicone contamination on rotors, pads, or calipers is a serious safety issue. Engine bay application near ignition sources is not recommended because the propellant is extremely flammable.
Amazon feature bullets state the high-silicone formula does not attract dust or dirt, and the review corpus does not surface staining complaints. The petrolatum carrier can leave a minor surface sheen immediately after application, but owners do not report problematic residue buildup. Keep the spray off painted panels and any surface that may need future bodywork or adhesive bonding; silicone residue is difficult to remove and prevents primer and paint from bonding properly.
