Has anyone had their clear coat frost, but only on areas where an acrylic sludge wash was applied? I've had this happen with Model Master clear flat lacquer and Polly Scale clear flat acrylic, but it only seems to happen if it gets wet with water. Its weird because it only does it on panel lines, in recesses, etc. anyplace where the wash settles. Obviously it has to do something with the wash, but I don't know what?
