Aerosol paint composition and metallic mechanical part coated with same

A metallic mechanical part coated with an aerosol coating composition, the aerosol coating composition comprising a modified alkyd resin, inorganic microparticles and an organic solvent, wherein

• the modified alkyd resin includes the organic solvent, a dispersion stabilizer made of a vinyl based polymer soluble in the organic solvent at 20° C. when the dispersion stabilizer has a solid content of 50 mass % and has a viscosity of 300 P or less and an alkyd resin soluble in the organic solvent or a dispersion stabilizer made of said alkyd resin alone;
• and dispersion particles made of a vinyl based polymer insoluble in the organic solvent at 20° C. when the vinyl-based polymer has a solid content of 50 mass % and has a viscosity of 300 P or more;
• the inorganic microparticles are made of one selected from silica, titanium oxide, zinc oxide, alumina, calcium carbonate, talc and clay;
• the inorganic microparticles have a mean particle diameter ranging from 1.0 μm to 10.0 μm;
• and
• the inorganic microparticles have a content ranging from 0.1 mass % to 5 mass %.
