Well, I work on a car wash as a detailer and my co worker was working on this expedition with a lot of scratches. He was using a rotary and saw how fast it cuts and effective it is. One of the problem he's doing is he kept the rotary tilted to one side and it slings a lot of product and the car has some holograms after he was done. So i asked him if i can work on one panel. So he let me but I couldn't keep the rotary to stay flat and it gets all over the place. How do you guys handle a rotary?
