It protects metal surfaces on heavy-duty trucks and trailers—frames, underbodies, wheel wells, fuel tank brackets, and chassis components—from moisture, road salt, and corrosion. The coating also helps dampen road noise and seals seams to prevent rust. It's a general shop supply used for underbody preservation and restoration.
