Tom, I usually have a can of Testors Dull-Cote handy for when I want aluminum wheels, aluminum bumpers, and of course Moon tanks too. I just spray these chrome plated pieces with one or two light coats or Dull-Core and they're "good to go." Moon tanks always come plated in the model kits, however 1:1 Moon tanks are made of spun aluminum. Also blowers come plated as well, but 1:1 blower casings are made of materials that can't be chrome plated, however they can be polished to look chrome plated. I sometimes use Dull-Cote on the blowers as well. I hope this helps.
