Plainsman's thread link gives some good advice, however, you have to recall that Plainsman himself was initially complaining about scratches in the rear cutout, and was told over at Slowtwitch to fix it only if he could see it while riding (i.e. with the wheel on). Ha, just some good natured ribbing here. But when he says he's trying to see if he can forget about it, not sure I believe he can do it. :-)
(and this coming from a guy who totaled his 2008 P2C Dura Ace three weeks ago avoiding a car who turned without warning right in front of me from the oncoming lane, so from where I sit a few scratches to your "baby" aren't too bad. I'm fu*ked up pretty bad, but I now am waiting for insurance dispute to clear before replacing my baby).
