Abstract
A metallic member, which is subjected to rust-preventive treatment, includes a metallic substrate, a zinc composite coating film, and a coating layer. The metallic substrate is formed as a predetermined configuration. The zinc composite coating film is disposed on the metallic substrate. The coating layer is made by coating and drying a coating composition on the zinc composite coating film. The coating composition includes a coating vehicle, a body pigment, and a rust-preventive pigment. The coating vehicle includes an organic solvent, and a resinous material being dissolved in the organic solvent. The body pigment is dispersed in the coating vehicle. The rust-preventive pigment is dispersed in the coating vehicle.
