I use a rotary and polish pad. I prime the pad, then put lines on the car panel, 2-3 lines per panel. I tend to put polish on the pad or smear it on to bumpers. PwC doesn't dust badly, so I don't mind using enough. With a rotary, it works in quickly, and I put damp cloths on the bottom of the windshield over the rain trap to catch sling and dust.
I work at 1000rpm, smearing the product across the panel. I boost up to between 1400-2200rpm. Usually takes 3-4 solid, slow moving passes to work the product in to a glossy finish, about 45-75 mins per car.
On a PC, I'm guessing it is a lot slower.
My only tip (other than the rags) is to be patient, take your time, and move with the body lines (front to back on all panels except side to side/left to right on trunk and bumpers). Working with natural body lines is a big deal.
