Title: Method of restoring damaged foul release coating area on a metallic surface, and surface obtained thereby

Abstract: A method is provided for applying a two-part RTV silicone tie coat directly onto damaged foul release coating area on a metallic substrate to enable restoration procedures. The direct application onto aged epoxy or silicone surface of an effective amount of an aminoalkyltrialkoxysilane, such as .gamma.-aminopropyltrimethoxy-silane, in a two-part RTV silicone tie coat, has been found to provide cohesive failure results with directly applied two-part RTV silicone top coat. A treated metallic substrate is obtained thereby.
