I would do no more then hand rag and paste polishing of any anodized bike part. One reason to have the anodize layer present and intact is that it is the better protective layer WRT corrosion goes. That it lends it's self to a pretty look is the icing on the cake.


Most companies that do anodize their parts will state that in a spec sheet or published form as it's a selling point. Back in the day it was general knowledge that Campy anodized their parts. It was not hard to look at the finish color and texture and know it was an anodized one, or not.


But as long as one cleans the parts and keeps then from corrosive elements (like sea water) bare polished AL can and does stay shinny for a long time. The issue is when said parts have nooks and crannies or otherwise inaccessible spots, like around spoke holes on hubs or between the arms of a brake caliper. Andy.
