A three-coat one-bake type coating process for forming a multilayer coating film which attains high efficiency and brings about an excellent finished appearance. A three-coat one-bake type coating process includes applying an intermediate coating material, applying a finish base coating material, applying a clear topcoating material, and drying, wherein a two-package type coating material containing an isocyanate compound as the crosslinking agent is used as the intermediate coating material, whereby the surface fluidity of the intermediate coating is improved to make the coating surface smooth and the mixing of the intermediate coating with an upper layer and/or the volume shrinkage of the intermediate coating due to the component eliminated by curing are inhibited to give coated members having an excellent finished appearance. |
