New PC users, you should definitely try the Meguiar'a Dual Action Microfiber Correction system. Or at least the Microfiber pad and D300. You will see a huge output from your PC. Considerably reduces correction time.

I also set people up with green buff and shine pads and either Ultimate Compound or M100 for increased cutting with foam pads. Softer than traditionally designated foam cutting pads, but larger pores, for better cutting, and cooler operating temps - all with less vibration. Back in the 2000's they were once designated as light cut pads. It wasn't until dense pads and high pressure became fashionable they were relegated to a "polish" pad. However, there is more than one way to "skin a cat", and the green B&S, or Pink Lake Country work great with the PC to remove defects. Works best with non diminishing abrasives found in the afore mentioned Meguiar's products, light pressure, and anywhere from speeds 4.5-6. Doesn't work with high preasure.
