Correct, the white residue is dead, oxidized gel-coat you abraded off.

Anytime you're working on major oxidation, be it a gel-coat boat or a single stage paint job, you're going to see the color of the pigment building up on your pad and you do want to clean your pad often.

If you don't clean your pad often here's what happens,

1. You grind the removed, dead oxidized gel-coat back into the next section you buff.

2. You dilute or weaken the strength of the fresh product you use next as it mixes with the residues.

3. The resulting film you leave on the boat will become harder to wipe off and this will tire you out.

So yep... clean your pad often. In a perfect world you would clean it after each section you buff.

The Flex is a powerful tool. Foam cutting pads generate heat. It's normal. The good news is gel-coat is not as sensitive to heat as automotive clearcoats.

Gel-coat is very different to buff than car paint. It likes wool pads on a rotary buffer to create a super high gloss shine. The downside is wool pads on a rotary will leave swirls/holograms scratches.

Gel-coat, like polishing aluminum isn't as forgiving as car paint. With car paint if you don't get the paint perfect during the compounding step you can clean it up a little more with the polishing step.

With oxidized gel-coat and aluminum you have to nail it during the first step. Less aggressive steps won't pick up the slack so to speak.
