My 56 has the original wheels (I believe) and hubcaps (I am sure), and though the hubcaps are pretty much toast, the wheels are in descent shape and I would like to clean/sandblast/paint or whatever is necessary to help them continue in service. My question is what would be the best procedure to follow to get rid of any rust and keep it from coming back, and also what would be the appropriate color to paint them. Right now they appear to be a dull black, but I do not know if that is original or not.
