So, I went to do a small area on the pwc last night and the compound almost immediatly turns black. So I'm left with a black buffing pad and this black residue on the pwc that can only be removed by using more compound on a clean rag and buffing by hand.

I'm using 3M compound and a foam cutting pad.

Sounds like you have some sort of other residue probably oil/gas on the hull. Is it a 2 stroke? Hard to say for sure but I would wash it with simple green then soap and water then hit it with the compound. If it still does it then keep compounding. You have to get all of the contaminates off so you can polish.
