First and foremost, you are either using too much polish or starting out too fast e.g. to high a speed.
Poorboy's polishes are top quality products and thus should not be dusting as you describe. Here is the best way to do it (and it will work for all polishes).
Take your pad, attach it to your PC, take your chosen polish and apply 4 small dots (essentially filling the little divots on the ccs pad), identify the 1 foot square area you are going to polish, tap the PC/pad combo on the four corners of the 1 foot square area essentially priming the panel, then turn on your PC on it lowest level, and begin a slow methodical movement back and forth covering your identified 1 foot square area, once you have effectively spread the polish, slowly turn up the PC rpm's and continue the methodical passes back and forth, then up and down, then back and forth, etc., until you have broken down the polish. If you do this correctly, you will have very minimal dusting, as you progress, the panel should appear first wet, then hazy, then the polish should appear as if it is clearing or starting to disappear. At that point you know the micro particles are broken down and the panel should be close to perfection for the level of polish for which you have chosen to begin.
Never, I repeat, never start with a level 3 (or most aggressive). Always start with a level 2 and a white pad with light to moderate pressure to assess the requirements of a more aggressive pad, polish or both.
