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 aspiration toxicity — thin, oily liquids can slip into the lungs if swallowed, causing chemical pneumonia.
If swallowed:
The aspiration hazard (H304) is about the liquid being swallowed and reaching the airway, not about breathing fumes during normal use.
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.

Only when: misting overhead
Beyond SDS: translated from the ingredient chemistry
No serious eye damage (H318) and no eye irritation (H319/H320) at SDS §2 mixture level · §11 explicitly states 'Serious eye damage/irritation: Not classified.' The DANGER signal word here is driven solely by the aspiration hazard (an ingestion/swallowing pathway, not an eye pathway), so the rubric's H304-only carve-out applies and eyes does NOT escalate to required. SDS §8 calls for safety glasses or goggles using the softener 'are recommended.' Misting overhead · spraying upward into window tracks or weatherstripping above eye level · is the named trigger for safety glasses.

Only when: prolonged use
Beyond SDS: translated from the ingredient chemistry
SDS §11 explicitly states 'Skin corrosion/irritation: Not classified' and 'Respiratory or skin sensitization: Not classified' · the SDS affirmatively negates the skin pathway. The H304 classification that drives DANGER is an aspiration/ingestion route, not a skin route. SDS §8 calls for gloves as a category baseline; brief incidental contact is low-risk. The situational trigger is prolonged or repeated handling, where the petroleum carrier can defat skin.

Only when: in enclosed space
Beyond SDS: translated from the ingredient chemistry
Aerosol format with a petroleum-distillate carrier. No respiratory irritation (H335), no acute inhalation toxicity (H330/H331/H332), and no respiratory sensitization (H334) at SDS §2; §11 confirms none of these classifications. For brief outdoor application or with the garage door open, no respiratory protection is needed. In an enclosed garage with the door shut, use ventilation or wear a respirator · SDS §8 calls for respiratory protection 'in case of insufficient ventilation,' an engineering-control-gated note rather than an imperative escalation.

Scope of these PPE tiers. The tiers on this page translate the product's Safety Data Sheet where one is published, plus its ingredient chemistry, into a comparable rating. They describe a formulation, not a situation: a tier is not a safety determination for any specific user, task, quantity, or environment. The manufacturer's label and use instructions govern how the product is handled. Where the product is used at work, the employer's PPE program and hazard assessment under 29 CFR 1910.132 decide what protection is selected, not this page.

TL;DR DANGER: the aspiration hazard means it can be fatal if swallowed and enters the airways, and this listing carries a California Prop 65 warning. Owners report squeaks and binding gone after one spray on rubber seals and window tracks; film life is average, and it isn't pure silicone, so keep it off paint.
This aerosol silicone spray targets rubber and plastic: door seals, window channels, trunk seals, and weatherstripping. Spray a light coat and let it dry; no wiping needed. Owners consistently report squeaks and binding gone after one application. The maker's durability claim isn't backed by community reports on outdoor seals, so expect average film life from a standard nozzle with no precision straw.
Best for car owners chasing a squeaky door seal, sticky window track, or dried-out weatherstripping; the film revives rubber and plastic well. Skip it for metal-to-metal contact like loaded hinges, fasteners, or chains, where a multi-purpose lubricant or white lithium grease is the right tool, and keep it off anything headed for paint or bodywork; residue is hard to remove.
DANGER comes from an aspiration hazard, fatal if swallowed and it enters the lungs, plus flammable, pressurized-aerosol physical hazards, so keep it from flame and heat. The safety data sheet finds no eye or skin irritation and no sensitization, so PPE stays situational, needed mainly for overhead spraying or a closed space. This listing carries a California Prop 65 warning even though the safety data sheet names no specific listed chemical. VOC content is high and the carrier is aquatic-toxic; use it outdoors with good airflow.
Safe for brief and normal-use contact with EPDM and neoprene rubber seals · no rubber degradation is documented by owners. The catch: the carrier is petroleum-based (an isoparaffinic C9-11 fraction plus a hydrotreated light petroleum distillate, per SDS §3), not pure silicone oil, so surface_safety is held conservatively at 6/10. Prolonged or soaking contact with rubber is not the intended use. For a higher surface_safety score, look for a silicone spray whose SDS Section 3 shows only the silicone active and propellant · no petroleum-distillate carrier.
The DANGER signal word is driven by three classifications in SDS §2: an aspiration hazard (the liquid may be fatal if swallowed and enters the airways), a flammable-aerosol physical hazard, and a pressurized-container physical hazard. The aspiration classification is specifically about the swallowing route · light petroleum-distillate liquid entering the lungs during vomiting can cause chemical pneumonitis. The flammable-aerosol and pressurized-container codes address fire and pressure risk, which is why the can warns against open flames and storage above 120°F. SDS §11 lists no acute toxicity, no skin or eye irritation, no sensitization, and no carcinogenicity, mutagenicity, or reproductive toxicity classifications · the DANGER label is not telling you the spray is biologically toxic in normal use; it is telling you not to ingest it and to keep it away from ignition sources.
Yes · the product listing carries the California Prop 65 warning, and the posted listing is the authoritative buyer-facing source on this. The manufacturer's safety data sheet doesn't name a specific listed chemical behind it; its state-regulatory section is simply silent, which is not the same as clearing the warning. Petroleum-distillate carriers like the one in this product can sometimes carry trace impurities below the concentration a safety data sheet has to itemize by name, which is a common reason this style of warning shows up on petroleum-carrier aerosol products in general · that's background context, not a claim that a specific named chemical is confirmed present in this can. The warning itself should be treated as real and current no matter what the safety data sheet does or doesn't spell out.
No. Keep silicone spray off all painted panels, primer, and any surface that may need touch-up paint or body-panel adhesive bonding. Silicone residue is very difficult to fully degrease and prevents paint and primer from adhering · a known issue in body-shop work. Apply only to rubber seals, plastic trim, weatherstripping, window tracks, and hinge pivots · and mask or shield adjacent paint when spraying near body panels.
Both are aerosol silicone sprays built on a petroleum-distillate carrier, so the core chemistry stories are similar · the aspiration-hazard DANGER label, the California Prop 65 warning, and the high-VOC profile are all common to petroleum-carrier aerosol silicone in this category. The B'laster formula declares a simpler ingredient list in SDS §3 (two petroleum fractions plus CO₂ as propellant), with no acetone or heptane co-solvents. CRC's typical formula adds acetone and heptane fractions, which broadens the flammability and inhalation profile. Neither is a pure-silicone-oil formula · for that, look for a silicone spray whose SDS Section 3 lists only the silicone active and a propellant.
