In a coating film formation method in which the thermosetting water-borne color paint (A) is coated on the surface of the substrate, then a thermosetting water-borne paint containing color pigment and/or glittering pigment (B) is coated on said coated surface, and, after predrying as necessary, a thermosetting clear paint (C) is coated and after that said 3-layer coating films of (A), (B) and (C) are simultaneously cured by heating, the solid content of the wet coat is controlled by an air jet step in which the air, whose temperature and/or humidity are controlled, is jetted from behind the paint nozzle in approximately the same direction as the atomized particles of said thermosetting water color paint (A) move to the surface of the substrate, when said paint is coated, around the spray pattern so that the air touches said pattern.
