I have painted my truck a few months ago and now i am seeing cracks or lines, separation in the finish. Did i apply to much clear? or is it a problem with cheap paint (clear ). If memory serves i put about 4-5 coats of clear ( about 7/8 of a gallon ) this is on a dodge Dakota P/U. I had some orange peal so i wet sanded it all out and buffed. I looked great b/4 the cracks/lines.
