Nu-Finish on the wheels does work great! I've had a bottle of the stuff sitting around for 10 years.. used to use it when all I could afford was older cars... it does work great. Lasts a long time - Consumer Reports says it resists a weekly car wash for a year.. I put it on all 4 wheels... did the front two when I removed them to put in hyper white fog light bulbs.. works great... Now brake dust comes off extremely easy when washing the car... or in between washes, a quick wipe now works wonders.. Thanks to whoever posted that tip!

Another side note - a few years ago, I had an Eclipse with 18" aluminum wheels - they got very dirty. There was a product I was using - an anti brake dust spray product. You spray it on - let it dry, and it basically does the same thing as the Nu-Finish - only I think it also made brake dust build up slower. I can't seem to find it anymore. Has anyone else seen this stuff? I'd like to buy more if I could find it! I bet the Nu-Finish with the anti brake dust spray would be insane!!
