Overview
Built for the job.
Bumper coater aerosols are a line of advanced coatings formulated to restore the OEM finish on automotive bumpers and plastic cladding.
Bumper Coater™ 39073 Trim Paint is a 16 oz aerosol gloss silver coating formulated for automotive trim, bumper, and plastic repair applications. It provides a durable, high-gloss finish that matches OEM specifications on painted or primed substrates.
Technical advantages include a rapid flash time of 5-10 minutes between coats and coverage of approximately 10 sq ft per can at 1 mil dry film thickness. The formulation is compatible with OEM plastics, primers, and existing paint systems, delivering consistent color build without excessive buildup.
Use requires standard PPE: eye protection, gloves, protective clothing, and a respirator. Apply in a well-ventilated area; the product has a flash point of -42 °C and is classified under multiple GHS hazards (acute toxicity, flammable gas, carcinogen, etc.). Follow H-statements H222, H280, H304, H315, H336, H351, H361, and H373 for safe handling.
