Lack of gloss on a painted surface is usually due to one or more of the following:
· Oxidation of the exterior paint layer
· Scratches in the exterior paint layer
· Lack of a protective coating on the exterior paint layer
Oxidation is the dulling of the painted surface that occurs when the sun’s ultraviolet rays deplete the paint’s natural oils and resins. Scratches prevent light from reflecting uniformly from the painted surface, which limits gloss. In order to restore gloss, oxidation and scratches must be removed.
