Disclosed is a coating method for forming a metallic coat, comprising the steps of applying to a substrate a base coating composition containing a metallic pigment and applying a clear top coating composition to the coated surface, the method being characterized in that the clear top coating composition is a curable one comprising as a main component a nonaqueous dispersion of a polymer of a radically polymerizable monomer, said dispersion containing as a dispersion stabilizer a fluorine-containing copolymer comprising a hydroxyl group-containing monomer and a perfluoroalkyl group-containing acrylic or methacrylic monomer represented by the following formula (1) (1) wherein R is a hydrogen atom or a methyl group, n is an integer of 1 to 11 and Rf is a straight chain or branched chain perfluoroalkyl group having 1 to 21 carbon atoms.
