ABSTRACT:
A method for applying multiple layers of coating compositions on a previously painted substrate by first applying a primer coating and then applying over the primer coating a top coating that matches the color of the painted substrate at less than complete hiding to achieve a color match of the top coating and the previously painted substrate; the improvement used is to apply a gray or white primer coating at complete hiding having a reflectance in its dried state essentially the same as the top coating measured at the wave length of minimum absorption of the top coating.
