Can anyone please give me some advice on using #9 or changing to DACP. I am currently using PC with cma yellow cutting pad. Results could be better in my opinion. I am not sure why the swirl marks are not all going away. Is it that the #9 in not strong enough, or maybee the speed of the PC (5), or not letting the product work its way in. Is DACP a more aggressive product, and if so how much different is it to use than #9. Any advice would be greatly appreciated...
