Paint Oxidation (Faded Paint)

It is most common on single-stage paints and on red and black cars. Horizontal panels such as the bonnet and roof fade first. Light oxidation can often be polished away. Garage parking or a car cover reduces sun exposure.

Ultraviolet light and oxygen break down the paint binder and pigments at the surface.

Severe oxidation that has reached the base coat needs a respray. Regular washing and wax or sealant protection slow it down.
