It's still not as good as I want but the boat lives out side all year with a cover that doesn't protect the black at all. I bought a 3m foam Black pad and slowed the speed on the buffer all the way down. But it still leaves a resedue of finesse on the hull. I have to come back and rub it off by hand.
Left side of the pic is wet sanded and the right side of the pic is all the way to wax.
