A rust-proof coating proposed as one aspect of the present invention, which does not contain a hazardous metal such as chromium and is able to form a thin coating in which crack generation is inhibited even after a baking treatment at a high temperature, comprises based on the whole composition, 5 to 40 % by weight of an organic silicon compound, 0.05 to 5.0% by weight of an organic titanium compound, 20 to 60% by weight of one or more metal powders selected from the group consisting of zinc powder, zinc alloy powder, and aluminum powder, and 10 to 60% by weight of an organic solvent. A coating having excellent anticorrosive properties can be formed by coating the above-mentioned paint composition followed by heating at a temperature of from 200 to 400 degrees C.
