There is provided a method for forming a brilliant coating film with an excellent brilliant appearance by using aqueous first and second base coating compositions without preheating the applied first base coating composition. In the method, the aqueous first base coating composition is applied to a substrate to form a first base coating, the aqueous second base coating composition is applied to the first base coating to form a second base coating, a clear coating composition is applied to the second base coating to form a clear coating, and then the uncured coatings formed are simultaneously heated and cured, under controlling the solid contents of the first and second base coating compositions and the ratio therebetween, or the brilliant pigment mass concentrations of the base coating compositions and the ratio therebetween, or the mass ratio, the evaporation rate, and the solubility parameter of a solvent contained in the first base coating composition.
