I'm rolling the inner lip. It will possibly mess up some of the paint, I was working on getting some extra fenders, but the car was taken from Chesterfield Auto Parts before I got to get the fenders from it. If it is done gently and heat is applied it usually can be done without damaging the paint, if a roller is used. I've done it many times using things like baseball bats and dowels and rolled them out but you A) Can't roll as much B) Can't control it as well and C) Damage the paint doing it that way. If done with a roller properly it can be done a lot with out damaging the paint.
