New rims, protection?'s

[Boss 5.0]

I just got a new set Of American Racing Polished Salt Flats for my 55 Chevy. What is the best way to keep these looking their best? I once had someone tell me the best way was to wax them. Is that any good? In the past I had a set of TTII's that dulled down in about two weeks and never looked as good as new again no matter what I did.

Any suggestions?? Thanks...
