RE: Rust spots
I haven't tried this but I'm wondering if you could get them good and clean, free of rust, wipe them off with paint thinner, let that dry, then spray some clear laquer (like Krylon in the rattle can) on them. Might last a little longer than wax. If I were trying this, I'd probably mask off all but the middle of the rim where the spokes attach.
Now, Skip would say just paint the rims black because chrome is evil.
