Gravelgard is a solvent based stone chip protection system based on rubber and resins. Gravelgard forms a tough, elastic, black protective film that dries quickly and can be painted over. The product is also suitable for enameled surfaces. Gravelgard is recommended for bumper spoilers, rocker rails, and wheel arches due to its good adhesion to most underbody materials. It forms a protective film that reduces noise and vibrations in the body. That is why Gravelgard is also highly effective as a sound absorbing coating for doors, hoods, etc.
