Abstract: Disclosed is a method and apparatus for drying a coating film (4a) on an exterior panel of a box-shaped workpiece (4), wherein radiant rays, and warm air having a temperature less than a hardening temperature of the coating film (4a), are supplied simultaneously and directly to the coating film (4a). The method and apparatus of the present invention can dry the coating film (4a) on the exterior panel of the workpiece (4) within a relatively short period of time, without causing a negative effect on a surface quality of the coating film (4a).

Abstract: The invention relates to a method for forming a multilayered coating film having a bright feel specific to a metallic coating film and a fineness of a luster color pigment with controlling the miscibility between each coating film when final coatings comprising an intermediate coating composition, a base coating composition and a clear coating composition are applied in this order by a wet-on-wet method to form coating films. The method for forming a multi-layered coating film comprises a step of applying an intermediate coating composition, a base coating composition and a clear coating composition in this order on a substrate formed with an electrodeposition coating film, and a step of baking and curing the applied three layers simultaneously, wherein the base coating composition contains crosslinking polymer microparticles and a nonaqueous dispersion resin.

Abstract: Painting a vehicle body comprising an exterior body portion, engine and cargo compartments and an interior door portion all of which are applied with an undercoat is completed by applying a gray intermediate coat to the exterior body portion, an intermediate coat to the engine and/or cargo compartments, a base coat comprising a single color base coat or a color base coat and a bright base coat to the interior door portion, a base coat comprising either a single color base coat or a color base coat and a bright base coat to the exterior body portion, a clear coat to the interior door portion and a clear coat to the exterior body portion in this order, each of the applications of coat being performed while coat layers formed preceding the each application of coat remain wet, and then baking and drying the coat layers all together.
