colorsanding/polishing paint... been a while

I use 1500 and 2k with block but have a 3/16 DA and 2k, 3k and 5k 3m trizact disc's for finish sanding. It IS expensive. They can get you to almost a polished finish without using compounds. It does cut fast so I use them on flat panels and block on the rest. I don't do it enough anymore to have developed a good technique with the DA yet.

I still use a rotary buffer some things you just cant change and I prefer to hand block sand as I get a better feel.
I first buff with a wool pad using the 3m 3-step perfect it compounds changing pads with each step. white, black, and blue also 3m.
