mottling is un-uniform metallics and streaking, like a blotchy paint job or the lines you get whe nthe metallics sag!!!Originally posted by OG 76@Nov 8 2003, 07:09 PM
if the car was not taken to metal and sealed and primed it could be the old paint absorbing the base coat and lifting it up off the body. But that is actually called something else like checked paint. If it is doing that then you would have to take the old paint completely off and prime the car for the base coat.
