Slight thread hijack. After cleaning, I used to treat the wheels with Poorboy's Wheel Sealant to make brake dust removal easier. Good product but I recently tried Blackfire Wet Diamond Sealant (I know it's meant for the body panels) with very good results. Less dust seems to stick and it's even easier to clean what does stick.
