By virtue of the fact that the ceramic coating protects the car’s exterior with a hard surface, it reduces the risk of stone-chip. This significantly decreases the potential for the vehicle’s bare-steel body panels to be exposed to water and salts that lead to oxidation, better known as rust. It is important to understand that, although the coating does offer an additional layer of protection against corrosion, it is still possible for stones to breach the ceramic film allowing rust to develop.
