Polishing grille

Hey all, just a quick question about polishing trim. I just bought a set of grilles and bezels for my '67 Fastback and while I know you can lightly sand and polish stainless trim, is there anything I can do on the bezels? What are they made of? They are in great shape structurally, no dents or bends, but they have some pretty mean scratches here and there. Not looking to go crazy on them, the car will be a driver but I'd like to shine them up as best as they can be. Thanks for any tips! Rob
