I'm getting ready to buff out my sons Focus. It's a black 2006 and has real bad swirl marks and some minor scuffs. Just wanted to get some opinions on what compounds to use. I've got a dewalt buffer and have tried meguires #2 followed by a glaze and then some syn wax. I have both the white and gray foam 3m pads. It turns out nice, but then buffing swirls get very obvious after a couple of washes. Any suggestions from the pros ??
