Bought this to repaint a door on my friends car after we accidently ran a die grinder with 60 grit sandpaper across the door.....trying to buff the whole car and we accidently used the wrong disc. Wasn't paying attention when I ordered it and thought I was ordering a quart not a touch up pen so ended up having to order the quart from a body shop but this works great for touching up all the rock chips he had in his paint from all the gravel drifting he does. Would but it again!
