Well I typically finish with 4500. Would I get better cut from the 1500 by using a pad other than your yellow? I got some good results today, but did three "coats" with yellow and 1500 to get where I wanted. Then 2 with 4500 and one PL (didnt have time for 2). I find I do better if I pick one section at a time, even if I have to break it up over a period of days to get the car done. Tomorrow will do another door and the rear fender. Eventually, car will be ready for its new home, lol.
