Ditto to everything Perry just said. My vote is you must have single stage paint. Don't worry, unless you sit in one spot for 20 minutes on speed 6, I don't think you could get through a clearcoat that fast. All jokes aside, you shouldn't be pressing hard. You should be applying just enough pressure for everything to work but not enough to bog the machine down, and keep the pad moving very slowly, almost a snail's pace, just don't stop.
The car looks great to me, I say keep up the good work!
