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™ 39103 is a 16‑oz aerosol spray formulated for flexible, high‑gloss black finish on automotive bumpers. It is designed for quick, uniform coverage of up to 10 sq‑ft at a 1 mil dry film thickness (DFT), making it ideal for OEM repairs and refinishing of aluminum, OEM, and plastic bumper substrates.
The product offers a flash time of 5–10 minutes between coats, allowing efficient multi‑coat builds without sacrificing adhesion. Its solvent‑based formulation provides excellent flexibility and impact resistance, while the aerosol delivery ensures consistent atomization for smooth, bubble‑free finishes.
Due to its flammable nature (flash point –42 °C) and listed GHS hazards, appropriate PPE—including eye protection, gloves, protective clothing, and a respirator—must be worn. Apply in a well‑ventilated area and follow the H‑statements (H222, H280, H304, H315, H336, H351, H361, H373) for safe handling.

Application Guide
- Clean and degrease the bumper surface; ensure the substrate (aluminum, OEM, or plastic) is free of contaminants.
- Apply the first coat of Bumper Coater™ 39103 from the aerosol can using a steady, overlapping sweep to achieve even coverage.
- Allow 5‑10 minutes flash time before applying additional coats; repeat as needed to reach the desired finish, typically 2‑3 coats for full coverage.
- After the final coat, let the finish cure to touch‑dry before handling; no special cleanup is required for the aerosol can.
