Abstract
Disclosed is a coating method comprising the steps of applying a color coating composition, applying a coating composition containing a pigment capable of producing a metallic effect to the layer of the color coating composition and applying a clear coating composition to the layer of the pigment-containing coating composition, characterized in that the color coating composition is able to form a layer having a Munsell value of 0 to 6; that the pigment-containing coating composition contains an iron oxide pigment and a vehicle as main components, the iron oxide pigment being iron oxide particles which contain at least 80% by weight of .alpha.-iron oxide crystals and which are each coated with titanium dioxide; that about 90% by weight or more of the iron oxide pigment has a longitudinal size of about 30 .mu.m or less than 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 is about 0.1 to about 30 parts by weight per 100 parts by weight of the vehicle (as solids).
