I agree with drewski on every point he made. I've tried AIO then SG (3x) on my wheels and it does make them very easy to clean. Yet, with the PB's WS, I definitely notice less brake dust buildup in addition to the wheels being very easy to clean w/ just soap and water. This is Audi brake dust which is almost as renown as the infamous BMW/Mercedes dusters.
I have been questioned by certain "non-believers" before that they didn't accept that a dedicated wheel sealant was any better than say KSG or Z2. There counter was why not use it on the rest of the car if it's so good. I can't answer their criticisms, but I did the product test for myself and my results proved the PB's works for me.
