Finally stopped raining long enough for me to give this Griot's polisher a try. I used Menzerna 2500 and a LC white pad and the results were decent. Swirl marks are minimized a lot but not completely gone. I think maybe I need more cut than the white pad has? I say this because I had to put the polisher on speed 6 before I really started to notice any improvement. And that polisher is very LOUD at that speed. Bearing down on the polisher didn't make any difference. I seemed to get the best results by turning the polisher all thew way up to speed 6 and not pushing down on it much at all. That was also a lot more comfortable than trying to push down on it. Maybe I would be better off with a Flex?
