Yeah, I don't think I'll have any problems with corrosion, but damn I didn't expect the clear coat to come off this easy.Aluminum oxide is stable enough you shouldn't really have any corrosion issues.
I like the look of marks from repeated use on metal stuff. It's a sign they're getting used. Like getting a nice ass groove in your spot on the couch.
I would agree with you on some things, about marks giving items character, but not my C-Six lol!
