Griot's Garage Black Shine Tire & Trim Coating

Shake the can, hold close to the sidewall, and spray the tire in a single steady pass — four tires takes about 5 minutes. The aerosol delivers a wet, high-gloss finish that dries quickly thanks to the acetone-heptane carrier. Real-world finish duration runs 2–3 weeks on a daily driver washed weekly, comparable to mid-tier petroleum gels and longer than budget aerosols. The spray pattern is tighter than mass-market aerosols, which is one of Griot's selling points, but overspray onto wheel faces still happens — community practice is to shield the wheel with a cardboard barrier during application.

Buy it if you want fast, gloss-heavy results and you don't mind the spray-and-shield workflow on wheels. The high-gloss finish and 2–3 week durability hit the practical sweet spot for occasional details. Skip it if you want the lowest possible health and environmental footprint — the aerosol propellant, acetone solvent, and heptane carrier together produce a DANGER-classification SDS that pump-spray water-based formulas in this price tier avoid entirely.

Aerosol product with a DANGER signal word, driven by the extremely flammable propellant (H222) and the heptane carrier's aspiration hazard (H304 — fatal if swallowed and enters airways). The acetone and heptane solvents add an H336 CNS-depressant classification (drowsiness or dizziness on heavy inhalation) — this is real chemistry, so apply outdoors or with garage doors open and forced ventilation. The SDS does not list a California Prop 65 warning. Environmental footprint is on the higher end of the category: heptane is aquatic-toxic (H401 acute, H412 chronic) and the total acetone+heptane VOC content is in the 300–500 g/L range. Apply outdoors and avoid hot surfaces or open flames.
