I usually use microfiber for cutting and foam for finishing. I use megs microfiber and lake country or hex logic foam pads. Can depend what compound or polish you're using too. It's a lot of personal choice to get the finish you want
I've used a few of the rupes foam and microfiber pads. I liked the microfiber pads and the white foam pads but didn't like the blue or green foam pads, again it's just personal preference. I would suggest getting one of each and see what you like using.
I use a megs g220v2 DA polisher but when I was using the rupes pads it was with a rupes 15 DA.
Hope that helps.
would highly recommend a paint depth gauge if you're doing a heavy cut on any paint
