I used a duster all last summer and it works PERFECT if you know how to use it. Couple key factors. Only use it on your car when the car is totally cool to the touch. Make sure you have a good wax or sealant on the car to help with the slickness because dust will come off SOOO much easier. If you don't garage your car I wouldn't use a duster. When you leave your car out overnight, the dew from the night/morning "sets" the dust on your car and then it's harder to get off and you'll have a greater chance of scratching the paint. When you do dust your car off, barley let the strands touch the paint. Obviously you should be using NO pressure at all. Hold the duster above the car, lower it until the strands just touch and that's all you need. I just waxed my wifes car yesterday and it sat out for a while and got a lot of dust on it, and it's black. I broke out the duster and it went over the paint like butter, removed ALL the dust and didn't leave a single swirl or mark of ANY kind. I'll wipe the car down every other day with a QD to keep the slickness up so when I do dust there are no issues. I've swirled up my paint WAY more using ONR than using a duster.
