And just to add....
Out of the 4 primary factors that influence and affect the paint polishing process, the pad brand and style is usually the least important AS LONG as you're matching the correct "type" of pad to the process.
By this I mean, if you're compounding you would normally be using a foam cutting pad, not a foam finishing pad. This is what I mean by matching the "type" of pad to the process.
The four primary factors that most influence the paint polishing process
1: Abrasive Technology
2: Pad choice
3: Tool choice
4: You and your technique
But the above does ASSUME the person doing the work is using correct technique. Correct technique isn't that hard to learn either. You're going to move a polisher in one of two styles,
1: Crosshatch pattern, overlapping your passes by 50% making approximately 8 section passes
2: Moving the polisher in the direction of the length of the panel - overlapping when possible making 10 to 12 section passes
Of course, paint hardness and/or softness is a factor. How deep or how shallow the defects are a factor. Buffing cycle is a factor. I'm not saying these things are not important I'm just saying the above 4 things I listed are the primary factors.
And then there's this,
Abrasive Technology - THE most important factor when it comes to polishing paint
