I know that is what it says in the book and all of the instructions, but I still have this hang up about it. I guess maybe from long ago when I used a constant speed one and burned through the paint along one of the lines they used to put in the sides of the older cars. It seems to be a very good kit and everything seems to work great. I really liked the clay and that remover as I had a car that was covered with over spray from a darn painting job on a building a block away and it felt like sandpaper. I decided since it was messed up anyway I would use the clay and see what happened and it came out as slick and smooth as you could want.
