I thought I recognized that GEPC bling bling. I almost did the same routine, except my swirls weren't too bad so I opted for SMR instead of DACP. Next time around though there's a couple of fine scratches and minor swirls left over dealer prep that I'll hit with the DACP.
I have an A4 and brake dust on the back wheels can get bad after a week (and that's driving a stick. I can't even imagine on an automatic). Anyway, try waxing your wheels. The brake dust wipes right off. I use Blitz on the wheels. Holds up very well to the heat. I'm still getting beading after about 2 months and at least 10 washes.
