Claims6
A process for coating a surface with a cured or a curable silicone-containing coating composition comprising applying a film-forming, silicon-containing primer composition to said surface prior to applying said coating composition thereby producing a primed surface, wherein said primer composition contains at least one primer-soluble, light-fugitive colorant which will retain at least some of its color for 24 hours and will subsequently become colorless in the presence of light, coating the primed surface with said coating composition before the primer on the surface becomes colorless and allowing any uncoated primer on the surface to become colorless in the presence of light.
