I've used Dull-Cote several times in the past on chrome wheels, front bumpers, and moon tanks to make those parts look like aluminum and they look great. Moon tanks are made from polished aluminum and are never chrome. Also Some of the super stocks had aluminum front ends with aluminum front bumpers and the Dull-Cote made it happen. I've also used Dull-Cote over painted surfaces to take down the shine. Try it!
