Overview
Built for the job.
Bumper Coater™ is a line of advanced coatings formulated to restore the OEM finish on automotive bumpers and plastic cladding.
Bumper Coater™ 39293 is a 16-oz aerosol spray formulated for rapid, high-quality finish on Honda black bumpers. Designed for professional body shop applications, it provides a uniform 1 mil dry film thickness (DFT) with an estimated coverage of 20 sq-ft per can, making it suitable for touch-up and full-panel work.
The coating offers a flash time of 5-10 minutes between coats, allowing fast recoat cycles while maintaining adhesion on aluminum, OEM, and plastic substrates. Its low viscosity ensures smooth flow and even film build, reducing the need for multiple passes.
Due to its flammable nature (flash point -42 °C) and listed GHS hazards, appropriate personal protective equipment-eye protection, gloves, protective clothing, and a respirator-is required. Apply in a well-ventilated area and follow standard first-aid procedures for inhalation, skin contact, eye exposure, or ingestion.
