I used Krylon Fusion metallic silver from Wal Mart...$5 a can. I also used an automotive-strength clearcoat a friend of mine had laying around (not sure of brand or price). After 4 coats of Krylon, the clear was probably not necessary. So far it held up great...it even survived my clumsiness while reinstalling the controls.
I, too, like the stock look, which is why I stayed silver. It is brighter than the factory, but that's okay. The doors I always thought would look better if they matched the bezel. I was looking for some other accent pieces to paint as well, but for now I think I like the minimalist approach.
EDIT: BTW...Ford wants $100 for a new bezel, so don't crack it during sanding :) I always check dealer prices before modding something to see how careful I have to be.
