All I have to say is be careful when you first get this. I used to detail cars and when I started I tried using one of these and it burned through the clearcoat. I believe anything that is over 2500 to 3000 rmp has the potential to burn clearcoat. To get rid of any scratches you actually have to heat up the clear and "move" it into the scratch and if you have no experience with it, its hard. The way I learned was they shop I worked for used to get hoods from a local junkyard and we would practice on them until we got real good. Just be careful with it and practice, you'll love this thing when you get used to using it, they are great.
