Second, on those wheels, if you run across that again and you have the regular Moose Wax, it works great on built up brake dust. I have a customer with the chrome Tork Thust wheels (5 spoke similiar to the Cragar SS wheels) that also had a ton of baked on brake dust. A few minutes with some MW and a terry cloth towel per wheel and they looked brand new again. They turned out so good that when he traded in his Suburban on a Silverado, he pulled those wheels and put them on the truck.
