Abstract
A method for coating a metallic substrate includes applying a powder coating composition to a majority of a surface of the metallic substrate, and applying an autodepositable coating composition to less than the majority of the surface of the metallic substrate. According to a preferred embodiment, the powder coating composition is applied to at least one continuous surface of the metallic substrate, while the autodepositable coating composition is applied to at least one discontinuous surface, such as an edge, of the metallic substrate.
