I’m looking at a used set of C5 wheels for my Vette. They are currently powder-coated in black and clear over silver. The silver is just clear over aluminum. I want them to be black and highly polished. Therefore I don’t want to use chemical stripper or I’ll screw up the black. So my question is, can I sand off the clear powder-coat? Will it sand simlilar to paint? Or is it so hard that it’s difficult to sand through?
