True ceramic coating is a long-term nanoscopic exterior automotive paint treatment and protectant that is applied in a liquid form and cures to form a hard layer on top of the paint. It can also be applied to wheels, brake calipers, and even glass to provide protection.

​

It chemically bonds to the surface it's applied to (when done properly) and can effectively eliminate small scratches and imperfections by filling them in and flattening the surface. Ceramic coating can't protect anything from serious damage or breakage, but it can add a layer of shielding, particularly from elements like rain and sunshine, that can keep a paint job looking better for longer.
