If it's not dirty a QD like Z6 is ok, but if it's dirty you are definitely inducing swirls by wiping.
Check out the Zaino line.
The California Duster is great if you use it very very lightly on dust. It is not for a dirty car.
If the car is dirty then you need to wash it.
I'm not a huge fan of dusters - they just increase the potential.
Just wash it every couple of drives and leave it uncovered, IMO.
Black, as you may or may not know, is the most difficult to keep from developing swirls.
I would wash the car after you drive it and definitely before you put the cover on it. There is more than just dust that builds up on the car during a drive on a nice day. You need to have lots of lubrication to remove whatever is on it. A wet cloth will not cut it.
Just my 2 cents.

An innovative product that protects automotive paint, while preserving our most valuable resource, water; enabling you to wash your car anywhere, anytime even inside your garage. It’s a multi-purpose product that serves as a shampoo additive, no rinse wash, quick detailer and clay lubricant, dilution rate 2-onces per gallon.
When sprayed on a dirty surface; surfactants break down the soil by releasing its surface tension or bond with the surface, encapsulating the soil particles, and the polymers provide surface lubrication to enable safe (marring free) removal
Methodology
Use a Monster Fluffy Towel for washing. Take one towel and wet it with as per directions. Wring it out and make a single pass per clean side of the towel. You can get 4-8 passes, with the towel folded in quarters. Each pass is then done with a perfectly clean towel surface and you're never rinsing any dirt out and releasing it in to your wash or rinse water. You can do the whole car with 2-4 towels. Apply no pressure to the towel, just glide it over the surface and only make one pass in one direction with a clean towel surface.
