ABSTRACT A coating composite provides extended corrosion resistance for substrate metals. The thin metallic undercoat of the composite contains combined metals. The heat curable and substantially resin free topcoat is established from a composition in liquid medium containing chromium in non-elemental form, which topcoat composition may further contain particulate metal. In addition to outstanding corrosion resistance, the composite can retain substrate weldability as well as achieving formability, while further enhancing paint- ability and weatherability.
