Abstract
A coating method characterized in that the method comprises the steps of applying a thermosetting coating composition containing a pigment to a substrate to be coated, applying a first clear coating composition to the coat to form a first clear coat, baking the two coats at the same time for curing, applying to the cured coats a second clear coating composition capable of forming a second clear coat having, when cured, a molecular weight between crosslinks of about 200 or less as determined by a xylene-swelling method and baking the second clear coat for curing.
