I'd agree with Nick....
For this project, we started with wool pads on rotary buffers but finished with the Purple Foamed Wool pads on the Flex 3401 with the heavy cut cleaner/wax.

While some of use were compounding the black gel-coat, others were tacklinging the white gel-coat cap using PFWs or Purple Foamed Wool Pads with our new Gel-Coat Heavy Cut Cleaner/Wax and Flex 3401 Forced Rotation Dual Action Polishers.
The fibers that make up the PFWs are encapsulated with foam and this creates a pad that offers good correction due to the fibers leveraging any abrasive or chemical cleaners while the foam helps to maintain good gloss for finishing.
The forced rotation Flex 3401 provides plenty of power without instilling swirls at the same time.
