I have read tons of posts on decal removal, and I am going to purchase the decal removal wheel (3M) today at a local store. I just want to be sure that this thing works (when used properly) WITHOUT removing any paint. I have a black '04 SJ and just want the all black look. So, this wheel will work without screwing up my black paint as long as I don't push too hard or spin it too fast? Sorry for yet another decal removal thread...just sounds like it would possibly mess up black paint.
