ABSTRACT:
Substrates, and especially aluminum substrates, are durably coated to include, as a basecoat, a heavily pigmented opaque coating composition consisting essentially of from about 45% to about 85% of a fluorocarbon resin and from 15% to about 55% of an acrylic resin, and having a pigment volume concentration sufficient to visually obliterate anything beneath it, said heavily pigmented coating composition being overcoated with a fluorocarbon topcoat containing from about 45% to about 85% of a fluorocarbon resin, and from about 15% to about 55% of an acrylic resin, on a resin solids basis, and having a pigment volume concentration of at least about 1%, on a film solids basis, the pigment content of said topcoat being insufficient to prevent the color of the basecoat from being easily seen.
