I have a set of HD t-bars that I bought off of E-bay a while back, and they have been in storage for a while. They are in great condition (i.e. no dings, deep scratches or bent), but they look kind of nasty on the surface. I am probably going to powdercoat them, but how should they be prepped? Is sanding o.k.? How about chemical stripping? I just want to make sure since I don't do anything to permanately damage them.
