ABSTRACT:
A coating method contains a coating step for spraying the surface of a coating substrate paint with a paint and a drying step for drying the paint coated thereon. The paint coated on the substate is then caused to flow or sag artificially within the coat in the drying step by application of an action from the outside at least in one of the coating and drying steps, namely, by heating or vibrating the paint coated thereon. During the flowing or sagging of the paint artificially, the substrate is rotated about its axis extending substantially horizontally in a longitudinal direction of the substrate at a speed which is high enough to rotate the substrate before the paint coated thereon substantially sag due to gravity yet which is low enough so as to cause no sagging as a result of centrifugal force.
