11 clear coat sprays tested to see which did and didn't cause Rustoleum gloss black enamel to blister. UPDATE: Douglas Grosch commented that using Rustoleum's flat black instead of their gloss black eliminates this problem. I tested it and he's right. After two light coats of Duplicator's Acrylic enamel clear followed by a third heavy coat I saw no blistering. On half of the test piece I coated it so heavily that it was dripping and it still didn't blister. Thanks, Douglas!
