Hey Nantucket -
Marstons Mills here - I have Team III wheels and they suggest usisng flour (as in baking flour) to polish the wheels. I haven't tried it but . . .
Never wash your wheels with a dirty cloth and be careful to hose off the brake dust before you touch the wheels. It is very abrasive.
The last time I polished my wheels I took them off, laid them on the ground and used Mother's aluminum polish. They looked like a mirror.
I
never wash my car and it has never been wet (lucky so far). No water = no water spots
Gotta go to sleep so I can get up early and kill some striped bass.
