KBS BlackTop is a single stage, moisture-cured 1K urethane chassis paint that seals frames, trailers, and suspension parts in a permanent, UV stable black finish without a separate clear coat. BlackTop applies by brush, roller, or spray gun over RustSeal, clean bare metal, primed, or previously painted surfaces, and comes in Gloss, OEM Satin, and Flat Black in sizes from aerosol to 5 gallon. BlackTop resists heat to 500F, holds 5H pencil hardness, and passes 2,000 hours of B117 salt spray when applied over two coats of RustSeal.
