メタリックベース塗膜５が形成される。Such processing steps are the same as conventional ones, and the next step is carried out according to the present invention. That is, after baking and drying the intermediate coating film 4, first, a baking type metallic base paint of the finishing color is applied to the entire surface of the car body 1. painted over. As this metallic base paint, a normal paint such as an acrylic melamine resin paint or a melamine alkyd resin paint is used, and a metallic base paint film 5 is formed on the intermediate coat film 4.

は生じない。At this time, in the side seal portion 1a, since the curing reaction mechanism of the metallic base coating film 5 and the clear coating film 7 is different from that of the coating film 6, as shown in FIG. 6 and the boundary between the coating film 6 and the clear coating film 7, the shrinkage phenomenon of the coating film occurs, and the diffused reflection of light results in an effect similar to that of forming a matte coating film. become. In addition, the side seal portion 1a
Except for this part, since the curing reaction mechanisms of the metallic base coating film 5 and the clear coating film 7 are the same, no shrinkage phenomenon of the coating film occurs.
このようにして艶消しのための特別のブースや乾燥炉を
用いることなく、しかも艶消し剤を用いることもなく、
車体１の一部に艶消し処理を施すことが可能になる。In this way, there is no need to use a special booth or drying oven for matting, and there is no need to use a matting agent.
It becomes possible to apply matte treatment to a part of the vehicle body 1.
