OH I also use a Dewalt body shop grade variable speed buffer. Have painted a few cars and was self taught with books and reading posts like these.Excellent advice, always buff off of an edge. Even with a PC you want to be careful on any sharp peaks and edges where the paint is the thinnest. I also use blue painters tape and tape off any trim. edges or whatever you do not want to get polish on or burn through. This is needed more so with the rotary than with the ROB but if you are a newbie it is better safe than sorry. Another thing you wil want to do is try to keep the pad as flat as possible. If you pull up on an angle you create a hot spot and in turn get swirls or even worst possible burn the paint.. You should also only buff until the polish turns clear and then remove the residue with a quality micro fiber towel. If you buff until dry you will produce swirls, even with a foam pad.Just make sure you have a buffer with variable speed so you can start at low RPM while learning to use it. Just think how slow your hand buff can move and how slow a buffer can go!! There is NO way you can burn with your hand. Just go slow. In order to burn the paint you have to be in 1 spot too long to build up heat(burn). Keep the buffer moving but Slowly!! You can stop and feel the paint getting warm. The most IMPORTANT is to THINK!!! when you are at an edge of the hood or a seam have the circular motion of the buffer PUSHING the material to the edge rather than pulling the edge toward the surface. Always away from the surface with buffer. After you see and understand how to use one it will be full speed. ALSO. only use the foam pads as a NEWBIE.
