Claim:
A method comprising coating a metallic section having a metallic surface that does not have an anticorrosive layer formed thereon with at least one layer of a first paint or polymer-containing layer to form a coated metallic section; forming the coated metallic section to produce a formed section; coating the formed section with a second paint or polymer-containing layer by applying to the surface of the formed section an aqueous composition which comprises water and a) at least one organic film former comprising at least one water-soluble or water-dispersed polymer having an acid number in the range from 5 to 200, b) at least one particulate inorganic compound, having an average particle diameter, measured in a scanning electron microscope, of from 0.005 up to 0.3 microns and c) at least one lubricant, and drying the second layer to form a particle-containing film on the metallic surface, wherein the dried film has a thickness in the range from 0.01 to 10 microns.
