Rubber coating on galvanized steel
I received my new and improved wheel wells from the manufacturer a few weeks ago. I was advised to etch them with vinegar and clean with alcohol, and apply the coating of my choice. I used a rubberized under coating that I bought at Napa Auto Parts Part # 8400. First off it never did dry quite right; it is wet in some spots and dry in others. Second it is falling off in huge clumps 3 days after its application. Bug and tar remover seems to take it of. Any advice, should I prime, sand, try something different?
