i accidently backed into my garage and scratched the black trim! con this trim be buffed out?

 

I don't think so - if you actually have GOUGES in it then I don't see how you could, say, sand those out.

Which peice did you mar? I'd just put up a "WTB" (Want to Buy) in the Marketplace for the peice you need. People are always replacing the trim peices when they install the aero kit, for aftermarket mufflers/exhaust peices etc. and usually they keep the spares in the garage until someone makes an offer.

 

the black trim parts are very reasonable in price new from the dealer and most come with the needed clips already installed on the part . its a easy snap in off snap on the new part on most of the pieces, maybe one screw or 2 and the rest are clips.
