Hey Guys,
Actually the Duster is alright for light dusting work, though it should be very light dusting, and I would recommend only doing it over a good coat of wax. The reason is, even though the fibers are basically safe, dust as a whole is an abrasive, and you are essentially not going to pick up all of the dust onto the duster which means you are still dragging some of that abrasive across the cars finish thus causing some form of micro-scratching which is not so good on nicely buffed out paint!
A safer alternative is to take a clean Microfiber towel, and either a bottle of Quick Detailer, or a clean plastic spray bottle and a 50/50 mix of distilled Water and Isobutyl (rubbing alcohol). mist the surface to act as a lubricant to eliminate the possibility of causing any scratching, and then wipe her down with the microfiber.
In Young Cruisers case, as long as your using a decent Paste Wax over the 3M Glaze your using you should be good to go, but if your not using wax after the Glaze, you will scratch right into the surface which could very slightly reduce the gloss especially on black.
Anyways, Go easy, and Ill catch ya later.
