I happen to work on alot of late model bmws and the paint is very hard on all of them. I need to use the rotary to correct the paint, however this color plus that the marring was pretty superficial - I was able to correct the sides with the pc, although I had to do many passes. On the roof/hood/trunk we found deep scretches that needed some heavy leveling.
