In a process wherein an organic coating is formed on a metallic surface by immersing the surface in an acidic aqueous coating composition containing dispersed particles of an organic coating-forming material, wherein said composition forms on said surface an organic coating which increases in thickness the longer the surface is immersed in the composition and wherein the coating on said surface tends to crack, the improvement comprising maintaining a non-oxidizing atmosphere surrounding the metallic surface from the time it is removed from the coating composition until the coated metallic surface is heated to fuse the coating.
