Hello guys, I gave my Buff and Shine microfiber pads a go today with the Porter Cable on my Black BMW. It was a brief trial, and I can't say it was a success, but I will work at it until I get it right. Right out of the gate, I had a tough time figuring out if the pad was primed because the microfiber is black, and you cant see the polish on the pad. I applied a generous amount of polish on the pad , put the pad on the body panel, and gave it some rotation, as they did in the Meguairs video. After that, I applied 3 pee size drops on the pad, as they advised in the video as well. I used speed setting 4.5 and I noticed right away that the machine was bogged down quite a bit, and moderate pressure would nearly stop rotation. I was using Menzerna FG400 and the Buff and Shine cutting pad. To avoid causing more defects that I started with, I figured I would get on here and see what you guys think I am doing wrong, or is this really how they are supposed to work. I was told that these pads like a good amount of pressure, and less speed than a foam pad, however, even with moderate pressure on speed 4.5 the pad nearly stops rotating. Thanks guys
