Abstract
Disclosed is a finish coating method for forming a finish coat, comprising the steps of applying to a substrate a base coating composition containing a 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 predominantly a nonaqueous dispersion of a polymer of radically polymerizable monomer, the dispersion being prepared by polymerization of the radically polymerizable monomer in an organic solvent in which the monomer is soluble and in which the polymer produced from the monomer is insoluble and in the presence of a fluoroolefin polymer as a dispersion stabilizer which is soluble in the organic solvent and which has a weight-average molecular weight of about 5,000 to about 120,000 and a fluorine content of about 1 to about 60% by weight.
