Pre-treatment of a metal, especially aluminum or zinc, prior to painting, by means of a complex halogen-containing phosphorus or aluminum containing chemically-bound molecules of water and/or an organic hydroxy compound. The preferred complex phosphate contains ethyl alcohol molecules and has an empirical formula of A1PC1H25C8O8, and is most conveniently used in solution in methyl alcohol or ethyl alcohol. |
