So I just bought a set of NOS Halibrand cobra II wheels. Gold centers. Oxidation on the rims. I like the machined or brushed look on the rims. Was wondering out to bring that back? Scotchbrite? Sandpaper? Are there any products I can use? What do the pros do? I'd like to seal the rim. Maybe clear coat?

Also some mild oxidation on the centers. I read online lightly pressure blast with plastic media. Will keep the gold coating on. Has anyone tried this?
