OK, so now you know what frame I ride. "SOMEONE" (not me) who lives where I do, has put a MASSIVE big scrape down the side of the top tube of my otherwise quite tidy alloy frame. It looks like it was done against one of the brick columns in the garage. The paint is wrinkled and bunched up at the edges of the scrape, not simply chipped off.
Should I trim or lightly sand the edges and then apply undercoat and touch up paint? I am concerned as much about the potential for rust as the cosmetics. So far, the bare alloy does not show signs of rusting (after several months). It's about a third of the way along from the seat tube end, so it dosn't get a lot of sweat on it, tho I do brush it with my knee occasionally.
I'm pretty pissed...it's the biggest ugliest scrape I've ever had on a bike....after years of training, racing, crashing, travelling in a bag through airports. It happened in my own garage, at the hands of a 'relative'. Ya gotta laugh (don't ya?, I can't really kill them, can I?)
