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™ 39163 Trim Paint is a 16 oz aerosol formulated for medium-smoke trim applications on OEM plastic bumpers and other compatible substrates. It provides a uniform, high-gloss finish suitable for factory-matched color repairs.
The spray delivers approximately 10 sq ft per can at 1 mil dry film thickness, with a flash time of 5-10 minutes between coats, allowing rapid build-up without compromising adhesion. It is compatible with OEM plastics and primers, offering consistent coverage while maintaining a VOC level of 701 g/L.
Use in a well-ventilated area and wear eye protection, gloves, protective clothing, and a respirator as required by the SDS. The product is classified as flammable (flash point -42 °C) and carries multiple GHS hazards; follow H-statements H222, H280, H304, H315, H336, H351, H361, and H373 for safe handling.
