I have only used Polish once, a 2008 BMW M5 is sapphire black metallic.
Polish- We compounded the car with M101 and a little D300 on a MF pad using the Dynabrade on a small flex rotary at max speed 6-3700rpm. The RIDS where somewhat deep so this took some extended polishing. Went straight to 3Ds polish using a white flat LC pad. Joey and I both started with a GG polisher at speed 5. The pad needs 6-8 pea sized drops to start as per the instructions. Work no more then a 2x2' area and apply medium pressure. When working the polish on the paint, it should be more on the wet side. If you use too little polish on the pad, you will get faint micro marring that is visible under extreme lighting on black metallic. It does not require an extended working time, like P085RD does to break down. The polish will not go totally clear when broke down but will change appearance and become more translucent. It wipes away with ease.
I then switched to the dynabrade using the same pad and it seems that it broke down a little quicker. If you try to work an area larger then 2x2' or dont use enough polish on the pad, you will get micro marring. After the first use of the pad, 4 pea sized drops should be about right. Again if micro marring occurs go over that area with more polish on the pad, maybe 6 drops. So you just have to play with the amount of polish you need on the pad, once you get that dialed in, you should be nice.
I also used polish with a 4" orange pad on a tighter area on the front bumper cover. It seemed to cut pretty well, not like M101 on a 3" MF, but not bad either. Joey and I are hoping that polish with a 6" orange pad will cut out surbuf/M101 micro marring which can be a little on the PITA side at times.
