Abstract

A coating composition includes a material adapted to form a coating; and a material that fluoresces when exposed to U.V. light or the material adapted to form a coating contains a U.V. blocker disposed on a U.V. indicator. A kit containing a U.V. indicator and material adapted to form a coating containing a U.V. blocker. Methods of coating a substrate with the coating compositions are also disclosed.

Claims

1. A coated metallic substrate comprising:

a. a metallic substrate comprising an automotive surface;

b. a U.V. indicator disposed on a portion of the metallic substrate; and

c. a coating comprising a U.V. blocker disposed on a portion of the U.V. indicator.

2. The coated metallic substrate of claim 1, wherein the automotive surface includes a two-coat finish comprising a clear top coat applied over a base coat containing pigment and metal flakes.

3. The coated metallic substrate of claim 2, wherein the metal flakes comprise aluminum flakes.

4. A method of protecting a metallic finish on an automotive surface, comprising steps of:

a. applying a U.V. indicator on a portion of the metallic finish disposed on the automotive surface;

b. applying a coating composition comprising a material adapted to form a coating and a U.V. blocker on a portion of the U.V. indicator; and

c. drying the coating composition.
