While I was parking at a resturant I had my friend spot me as there was limited parking and the best spot was to back up into the space. Well, she was waiving me back and long story short she didn't stop me in time and I backed into a lamp post with a concrete base. My rear bumper hit the concrete base and chipped pieces of my paint off (the area is approximately 2 inch wide and 3 inch high). Not the entire paint came off but just small pieces in that area and very noticeable. If I use touch up paint, it's still going to be noticeable with the size of the area especially when you look up close as you'll probably see little dots from the fill in. Is there anything I can do besides getting it repainted. I was thinking buffer (PC) but if the paint chipped off, will it work? Any info would be appreciated! BTW...it's a '03 black M3 and I keep the paint meticulously clean. TIA!
