Prices may varyAbout 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.
GHS hazard codes are quoted from the manufacturer’s Safety Data Sheet. PPE tiers below translate those codes and the listed ingredient chemistry; they are not CarCareTruth recommendations.

From the manufacturer’s Safety Data Sheet, Section 8
“H319 (causes serious eye irritation) per SDS §2 GHS classification (Serious Eye Damage/Eye Irritation Category 2A). Aerosol form factor escalates H319 to required per rubric: spray drift at arm's length makes ocular contact probable during application. SDS §8 specifies eye protection.”

TL;DR Lifts baked-on tar, asphalt overspray, and weathered bug residue in under a minute with cling foam; the DANGER label is real. The SDS classifies this as harmful if inhaled, H351 (suspected carcinogen Cat 2), and H361 (suspected reproductive toxin Cat 2): the SDS §7 directive requires outdoor or well-ventilated use, backed by the flammable aerosol rating and inhalation classification. Wear nitrile gloves and safety goggles, and plan a follow-up wash.
Spray on baked-on tar, asphalt overspray, or weathered bug residue, wait 30 to 60 seconds while the cling foam works, then wipe with a microfiber. The foam adheres to vertical surfaces: rocker panels, bumpers. Community on r/AutoDetailing, Autogeek, and Detailing World broadly confirms single-pass removal of week-old tar and dried bug protein within the labeled dwell window. Requires outdoor use; enclosed-space use is a real chemistry hazard, not a label formality. It leaves a thin oily film; plan for a follow-up wash. Quality score is 7.88, placing it above the category average on removal efficacy and versatility.
Buy it for infrequent spot treatment of baked-on residue: post-highway drives, road-construction zones. Skip it if you wash regularly and want bug-and-tar capability in the routine wash workflow; an aqueous wash-style product handles fresh residue without the inhalation risk or follow-up wash step.
The SDS assigns a DANGER signal word with H332 (harmful if inhaled), H315/H319 (skin and eye irritation), H317 (skin sensitizer Cat 1), H222/H229 (flammable aerosol, pressurized container), H351 (suspected carcinogen Cat 2), and H361 (suspected reproductive toxin Cat 2). SDS §8 specifies eye protection and gloves; SDS §7 directs outdoor or well-ventilated use only. Total VOC per SDS §9 is 40 to 60% by mass; the product carries a Prop 65 warning. The petroleum-distillate solvents are drain-destined aquatic toxicants when rinsed off exterior surfaces.
Community broadly confirms Stoner Tarminator is safe on cured factory clear coat at the labeled 30-60 second dwell time. For ceramic-coated paint, r/AutoDetailing threads recommend keeping dwell time short and rinsing promptly; extended dwell with solvent aerosols can affect coating durability. The product leaves a thin oily film typical of solvent formulas; a follow-up soap-and-water wash clears it.
30 to 60 seconds for fresh tar and bug residue; up to 2 minutes for baked-on residue per the product label. Community evidence on Autogeek and r/AutoDetailing confirms single-pass removal of week-old tar and dried bug protein within this window. Do not let the foam dry on the surface; the oily residue becomes harder to wipe off if it dries.
Tarminator's DANGER signal word is driven by the petroleum-distillate solvent base and hydrocarbon propellant. The SDS classifies it as Flammable Aerosol Category 1 (H222), with skin/eye irritation and inhalation hazard codes, and Category 2 suspected carcinogen/reproductive toxin codes (H351/H361). Aqueous wash-style bug & tar removers (Chemical Guys Bug & Tar Wash, Adam's Bug Remover) avoid the petroleum solvent and propellant entirely; they typically carry only a WARNING signal word.
Solvent aerosols can dehydrate rubber seals and may blanch some unpainted plastic trim with extended dwell. Community on r/AutoDetailing recommends keeping the foam off trim where possible and rinsing promptly if accidental contact occurs. For matte or satin finishes, test on a hidden area first; solvent aerosols are documented to affect some matte-finish coatings.
No. SDS §7 directs 'use only outdoors or in a well-ventilated area' due to the flammable aerosol rating and inhalation classification. The petroleum-distillate solvent vapor and hydrocarbon propellant accumulate quickly in enclosed spaces. Apply outdoors or with the garage door fully open.
