A coating method is a method for forming a multilayer coating film including at least one lower layer formed on a substrate and an uppermost layer formed on the lower layer, and the coating method comprises the steps of: preparing a certain curable coating material as an uppermost layer-coating material for forming the uppermost layer, and preparing a certain coating material as at least one lower layer-coating material for forming the lower layer; forming an uncured multilayer coating film by applying the lower layer-coating material and the uppermost layer-coating material on the substrate using a wet-on-wet technique; and curing at least the uppermost layer-coating material by subjecting the uncured multilayer coating film to a curing treatment.

With the use of a lead-free cationic electrodeposition coating composition containing a sulfonium-modified epoxy resin, an amine-modified novolak-type epoxy resin, and a blocked isocyanate curing agent as a binder resin, wherein the content of volatile organic components is 1% by weight or less, the coating liquid conductivity is 1000 to 2500 &#x3bc;S/cm, and the minimum film-forming temperature of the coated layer electrodeposited on an object to be coated is 20 to 35&#xb0; C., electrodeposition coating is carried out at or above the temperature which is lower by 2&#xb0; C. than the minimum film-forming temperature and at or below the temperature which is higher by 6&#xb0; C. than the minimum film-forming temperature.

A spray painting device having a first spray mechanism and a second spray mechanism located downstream of the first spray mechanism in an assembly line along which an automobile body is conveyed. A spray head of the first spray mechanism is fixed at a constant height when spraying paint onto a side outer panel portion which is situated over a front or rear wheel of the automobile chassis, and is moved up and down when spraying paint onto a side outer panel portion which is not situated over the front or rear wheel. A spray head of the second spray mechanism is located so that a constant distance is maintained between the spray heads and the side outer panel to spray a uniform coat of paint onto the side outer panel.
