Just about every space shuttle has ramp damage because of this. Just a really bad design. Look on the space shuttle owners thread. Lots of good ideas there and has been talked about to death. Can't quite remember how I dealt with it as I sold mine after doing a total restore.

It's call.. space shuttle crewmans club..prepare for liftoff.
Sorry, I would link it for you but I'm not at home and on my blackberry and this thing is useless. Lol.
Maybe someone could link it for you. Lots of amazing help for shuttle owners there.
