For those who doubt the wisdom of polishing out anodized parts, I can say that I've seen a number of bikes that had parts to which this was done (Chuck Schmidt is a polishing *god*.. ;> ), and the result is striking in the extreme.
Polishing with Simichrome will protect the now-bare surface for a good long while. The stuff leaves a protective film. I suppose one could wax such parts too.
