The invention is an article formed of a metal substrate with a protective, weather-resistant, transparent film overlying the surface of the metal substrate. The film is formed of a polymer that contains vinylidene fluoride and which imparts weather resistant properties to the workpiece. An adhesive layer is positioned between the protective film and the metal substrate and bonds the protective film to the metal substrate. The adhesive layer comprises an acrylic resin adhesive and a zircoaluminate adhesion promoter which enhances the bond between metals such as aluminum and the vinylidene fluoride containing polymer.
