Disclosed is a metallic coating method comprising the steps of applying a color coating composition, applying a metallic coating composition containing a metallic pigment to the layer of the color coating composition and applying a clear coating composition to the layer of the metallic coating composition, the method being characterized in that the color coating composition is able to form a layer having a Munsell value of 0 to 6; that the metallic coating composition contains a metallic pigment and a vehicle as main components, the metallic pigment being iron oxide particles of hexagonal platelike shape which contain at least 80% by weight of alpha -iron oxide crystals; that about 90% by weight or more of the metallic pigment has a longitudinal size of about 30 mu m or less and 40% by weight or more of the pigment has a longitudinal size of about 5 to about 15 mu m; that the thickness of the pigment is about 1/10 to about 1/20 of the longitudinal size of the pigment; and that the amount of the pigment used is about 0.1 to about 30 parts by weight per 100 parts by weight of the vehicle (as solids).
