Which is better. I have a black truck with some swirling on the hood along with some water stains. I tried the VM and #9 and they didn't do much. Iwant to go to something alittle more abrasive. I have never tried the 3M stuff before and I've heard good things about the DACP. I'm just a bit concerned DACP might be a bit too aggresive. Just looking for the thoughts of the experts out there.
