I never recommend using the California duster or any duster, actually I ask my clients to toss them away. Since the dirt and dust that lands on the vehicle is microscopic and very small, alot if it is very jagged and sharp. Alot like a kidney stone that humans excrete, but microscopic. So when you drag the duster across the car, ultimately you leave very fine hairline and micro scratches. But when you use a quality mist and wipe like we do, and 2 very plush microfibers the results are awesome. The mist and wipe will encapsulate the dirt, lubricate the paint and allows you to pick up the fine particles with one towel and then final dry and buff with the second towel. I maintain at least 60 to 70 high end vehicles weekly and after every wash we use this mist and wipe religiously for the final gloss enhancer!
