you get allot of dust during the bedding phase of new brake pads.
Michelin makes a brake dust repellent that I've gotten good results from.
I've been using

I've never seen anything so slick. Its like encapsulating the whole car in rubber. You'll notice it each time you close the door and your fingers just slide over paint.
its a good idea to wax the barrell of the wheel too. cuts down on the cleaning time.
