Any tips?

I've been going with the advice of everybody, and I've been taking it easy with pushing my tC too much, but I still hurt it yesterday. I was parallel parking, and I pulled in too fast and scrapped the right, front rim on the curb. It scratched up about half of the very outer part of the rim. It's really not all that noticeable unless you look at it closely, and I can almost convince myself that it's not all that bad of a scratch, until I look over and see how nice the other 3 still are.

Does anybody have any tips on what I can do to buff the scratch marks out?

Thanks
