Well it is obvious that I am doing something wrong. Recently I received my Porter Cable 7424 and several LC pads. When I use the orange pad with Pinnacle Advanced Swirl Remover, I end up having several small half circle marks in the paint. When I say several, I mean hundreds. I can easily see them when using a Halogen lamp. At first I tried a LC CCS pad, then when I noticed the marks I switched to a Low profile orange pad and had the same issue. I am starting with a speed of 3 and then going to 5 (as per the training video on autogeek.net). When I switch to a white pad and use the Pinnacle Advanced Finishing polish, the marks do not go away. After applying Pinnacle Souverin wax, you can still see them under the halogen lamp. I moved the car out into the sun today and when I am up close (less than a foot away) I can see them. So, what is it that I am doing wrong? I make sure that I do not apply to much pressure. I put the PC onto a scale and pressed down to figure out how much 20lbs pressure would be. However, I even varied pressure on different panels and got the same results.
