Abstract: Parts inexpensively coated that yet are difficult to mar. The reel body 1 of a double bearing reel is given as an example of a part superficially coated in accordance with the invention. It includes a metallic base portion 10, an oxide film layer 11, a substrate paint film layer 12, and a finishing paint film layer 13. The finishing paint film layer 13 is formed by the application of a self-mending paint material. Forming the paint film layer on the surface of the reel body 1 by applying a self-mending paint material by the self-mending function of the paint material thus restores scratched portions if the surface is damaged due to scratching or the like. Therefore, scratches due to injuries tend not to remain on the coated part and as a result, scratches are unlikely to damage the surface of the body of the part. Moreover, forming the layer by applying a paint material facilitates low cost production.
