I have a nice Puma which shaves fine enough despite my lack of skill in working it, but I'd feel better if I could do something about the blotchy appearance. I tried polishing it with Noxon, which did nothing. Then I realized that there isn't any rust or stains on the blade - the issue that causes that dark grey spotting must be the inconsistent wearing away of the factory chrome! So, if I want a consistent finish (I don't think I want to get it re-chromed, just consistent and clean-looking), what are my best options?
