45 degrees for cutting, 20 for finishing and flat for polishing. If your going to get into it get a medium cutting pad and a finishing pad. I prefer the Meguirs red medium pad. I like Final finish and tri cut II. You have to pick them up at a paint supply shop. Always tilt the leading edge of your buffing pad up and have the edge making contact with the paint trailing. The nice thing about old paint is if you are learning and you screw it up, well you screwed up old paint. Also apply your product to the pad and not to the paint. Some compounds start working on the paint as soon as they are put on and can mark the paint if left on.
