I'm with you on that one. I just polished out my Camaro yesterday, now I love the way Meguiar's D151 cleans up all the minor washing scratches/swirls (and even heavier stuff if a cutting pad is used) - BUT - it DUSTS! Not all that bad, but enough where you have to wipe down the car before moving onto the sealing step. I have found that misting a microfiber cloth with a Quick Detailer and using the weight of the cloth only will remove the dust without marring the surface. You might get a few QD smears, but in reality, that's a non issue compared to marring your perfect finish.
Oh yeah, and wind. Wind likes to blow dust all over your car and if you are using a spray product, blowing that all over the paint - this is why I switched to a gel tire shine. Since I dress the tires last, the spray would get all over and it's just not that easy to "wipe off" ANY type of tire protectant. Especially on a black car.
