Abstract: Provided are an aerosol coating composition excellent in a matte effect and capable of preventing co-rotation from occurring. The aerosol coating composition contains a modified alkyd resin, inorganic microparticles and an organic solvent. Herein, the modified alkyd resin is a non-aqueous dispersion resin which is a copolymer of a vinyl based monomer and an alkyd resin. The inorganic microparticles are made of one selected from silica, titanium oxide, zinc oxide, alumina, calcium carbonate, talc and clay or the like. The inorganic microparticles have a mean particle diameter of 1.0 to 10.0 μm, and a content of 0.1 to 5 mass %. There is also provided a metallic mechanical part coated with the aerosol coating composition.
