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, 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.

From the manufacturer’s Safety Data Sheet, Section 8
“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.”

From the manufacturer’s Safety Data Sheet, Section 8
“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.”

From the manufacturer’s Safety Data Sheet, Section 8
“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.”

TL;DR Reliable squeak-and-binding fix for rubber seals, window tracks, and weatherstripping, well-reviewed by a large owner base for the core lubrication job. DANGER-labeled: the petroleum carrier brings an aspiration-hazard classification, a California Prop 65 warning, and high VOC. Keep it off painted panels · silicone residue prevents paint and primer from bonding.
B'laster 16-SL is an 11-ounce aerosol silicone spray built on a petroleum-distillate carrier, aimed at the everyday rubber-and-plastic maintenance job: silencing squeaky door seals, freeing sticky window tracks, conditioning weatherstripping, and lubricating hinge pivots. Aim the can at the joint and apply a brief burst; the carrier flashes off and leaves a silicone film behind. It's highly rated on Amazon by a large owner base, with community consensus on reliable squeak and binding elimination on the first application; multi-month durability on outdoor-exposed seals is not independently validated, so realistic film longevity is closer to the commodity 4·8 weeks. Keep it off painted panels and any surface that may need touch-up paint or adhesive bonding · silicone residue is very difficult to fully degrease and prevents primer and paint from adhering.
Best for car owners dealing with squeaky door seals, sticky window channels, weatherstripping squeak, or binding sunroof tracks. Skip it for metal-on-metal applications · hinges under significant load, fasteners, chains · and for anything near brake components; white lithium grease handles metal-on-metal jobs and a penetrating oil handles seized fasteners.
DANGER-labeled, driven by an aspiration hazard from the petroleum carrier (a swallowing-route risk, not an inhalation hazard in normal use) plus the flammable-aerosol and pressurized-container physical hazards. SDS Section 11 explicitly classifies the formula as no skin or eye irritation, no skin or respiratory sensitization, and no acute toxicity · so eyes, skin, and lungs all land at situational rather than required, with the named triggers being overhead spraying, prolonged or repeated handling, and enclosed-space use. Carries a California Proposition 65 warning per the product listing · the petroleum-distillate fraction commonly carries trace aromatics at sub-disclosure concentrations that trigger the retail label. VOC is not disclosed in §9 but estimates above 550 g/L from the petroleum carrier in §3 · best used outdoors or with the garage door open, especially for the petroleum-carrier formulas. The silicone film stays on the surface, so it does not run off into drains; the main environmental footprint is the aerosol propellant and carrier VOC released during application.
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. The 2020-10-20 SDS §15.3 lists no state regulatory entries (the table is silent rather than disavowed), but the product listing-level compliance scanner flags the product, and that is the authoritative buyer-facing source. The hydrotreated light petroleum distillate in §3 commonly carries trace impurities · benzene, naphthalene, ethylbenzene, toluene, and similar aromatics · at concentrations below the §3 ingredient-disclosure threshold but at levels that trigger the mandatory California Prop 65 label at retail. This is a common pattern for petroleum-carrier aerosol products.
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.
