摘要：
A METALLIC SURFACE IS COATED WITH A POLYMERIC RESINOUS COATING BY IMMERSING THE SURFACE IN AN ACIDIC AQUEOUS COATING COMPOSITION COMPRISING POLYMERIC RESINOUS COATING-FORMING MATERIAL AND AN OXIDIZING AGENT. THE CORROSION RESISTANCE AND/OR THE SURFACE APPERANCE OF THE RESINOUS COATING IS MODIFIED BY RISING THE COATING WITH AN AQUEOUS RINSE SOLUTION CONTAINING HEXAVALENT CHROMIUM OR AN AQUEOUS RINSE SOLUTION CONTAINING HEXAVALENT CHROMIUM AND REDUCED FORMS OF CHROMIUM.
