I can tell you that anti-brake-dust paste/wax doesn't work worth crap. Amazing to me that a product can be marketed for a specific purpose, and make little (if any) difference! I suppose it might have resulted in my front wheels not looking like hell for 4 days instead of 3, but that's about it; I sure won't go to the trouble of applying it again!
I plan to try low-dust pads, but until then, the best solution seems to be "the old fashioned" approach, i.e., wash the car more often...
