Claim:
A method of forming a metallic tone glitter paint film comprising: applying a first base metallic paint for providing a sense of glitter with a metallic tone to an object to be painted, the first base metallic paint comprising: an aluminum pigment (A) of average particle diameter D 50 from 13 to 40 μm and average thickness from 0.5 to 2.5 μm; an aluminum pigment (B) of average particle diameter D 50 from 13 to 40 μm and average thickness from 0.01 μm but less than 0.5; and an aluminum pigment (C) of average particle diameter D 50 from 4 μm but less than 13 μm and average thickness from 0.01 to 1.3 μm wherein the ratio (A/B) of the masses of the solid fractions of the aluminum pigments (A) and (B) is from 10/90 to 90/10, the ratio ((A+B)/C) of the total mass of the solid fractions of the aluminum pigments (A) and (B) with respect to the mass of the solid fraction of the aluminum pigment (C) is from 90/10 to 30/70, and the total mass (A+B+C) of the solid fraction of the aluminum pigments (A), (B) and (C) is from 5 to 50 parts by mass per 100 parts by mass of the resin solid fraction; applying a second base glitter paint to the first base metallic paint wet-on-wet, wherein the first base metallic paint is in an unhardened state, the second base glitter paint comprising a very small scale-like pigment or a very small scale-like pigment, and an aluminum pigment (D), wherein the very small scale-like pigment is characterized by providing the metallic tone glitter paint film with a pearlescent gloss; applying a clear paint to the second base glitter paint wet-on-wet, wherein the second base glitter paint is in an unhardened state; and baking the first base metallic paint, the second base glitter paint, and the clear paint simultaneously at a temperature ranging from room temperature to 160° C., wherein the resulting metallic tone glitter paint film obtains both a pearlescent gloss and a metallic gloss.
