Zusammenfassung:	The present disclosed subject matter provides a method for improving the weathering resistance of a coating of paint on a substrate when exposed to adverse environmental conditions. More particularly, the method includes applying a post-production coating to a base coating, where the post-production coating contains a greater concentration of ultraviolet (UV) protectant as compared to the base coating. The UV protectant contained in the post-production coat migrates along a concentration gradient to the base coating, thereby enriching the concentration of UV protectant in the base coating. Although this application will help protect the base paint coating on a variety of substrates from damage due to environmental conditions, the present disclosed subject matter is ideally suited for motor vehicle coating applications.
