Abstract

This invention is directed to a coating method and to the product produced by such method. In the preferred practice of this invention, the method includes the steps of selecting a ferrous substrate, such as steel sheet preferably containing a first coating having certain corrosion resistant and adhesion-promoting characteristics, and applying thereto an outer coating of an organic resin containing a particulate metallic aluminum-zinc alloy which is between 5 and 95% by weight aluminum, balance zinc. Preferably, the particle size of said alloy is no more than about 10 microns. Such product is ideally suited for the subsequent application of a cathodic electrophoretic primer coat, such as widely used in the automotive industry.
