Excellent questions BeerGuy!
In general, I still recommend using the waterless wash product you have as a "quick detailer". Mist is on one panel and gently wipe the panel in one direction. Either flipping the towel over or using a separate towel, gently "buff" the section to remove any moisture or residue.
I highly advise against the California Duster! It does one thing very good, trap and hold dust and pollen. Even if you shake it out after every stroke, it does not release all the materials it has just picked up. The reason it grabs so much dust of your vehicle is that the individual fibers are coated in paraffin wax. As you use it more and more, it contains more dust and pollen. If you have never seen a microscopic picture of pollen is it pretty disturbing. It resembles the business end of a medieval mace!
Just remember, every time you touch your paint, you are abrading it to some degree. However, coatings and withstand the torture much better than just waxes.
The very best way to handle it is to just wait a few days until you can properly wash the vehicle. And, if you have compressed air or a leaf blower available that is even better than drying towels since you aren't even touching the paint to dry it.
