Has anyone used this? I ran over the top skin of a furniture delivery box truck which "floated" onto the highway in front of me and have a light scrape down the side of my car. You can't feel it with your nail but it feels rough when you slide your finger over it. It's not obvious unless you're looking for it but then it's in my face. It's a 2012 Elantra which is a highway warrior so I'm not freaking out about it but I want to do what I can to get it out. I've only ever done finish work by hand. I am considering getting a Groit 6" DA but for the little I'll probably use it are there any opinions on this unit?
