I use our Supreme Shine microfiber towels like you mentioned. Fold them in quarters and you get 4 pairs of sides to use when quick detailing a car. Spray the QD onto the paint, wipe with one side of the towel and then flip to the dry side and wipe again. Spray onto another area, wipe with the damp side of the towel, flip to the dry side and wipe again. As the "dry side" becomes a bit damp, refold the towel to expose a fresh "pair of sides" and continue on. Doing this, as mentioned, gives you 4 pairs of sides which should be enough, in most cases, to quick detail a Crossfire or even larger. With more dust, you'll flip the towel sooner, and that may mean grabbing a second or third towel.

With a true waterless wash like UWWA you want to start with two towels, one for the initial wet wipe and a second for the dry wipe. This is because you're using so much more product that towel #1 is going to get much wetter much faster, and much dirtier too. That means you'll be working through that towel fairly quickly. What I do is unfold that first towel as needed, drying with towel #2, until #1 is too wet and dirty to continue with. I then upgrade #2, my drying towel, to #1 status and grab a third towel for drying. I cycle through as needed, using as many towels as needed, until the car is clean. UWWA works great on glass, plastic trim, wheels, etc (do the wheels last though!!!!).

As for the rinseless wash product our new entry in this segment is D114 Rinseless Express Wash. The idea here is to add 1/2 ounce per gallon to a bucket of water. I usually use just a couple of gallons of water and therefore just an ounce of product. Don't put the product in first and then blast it with a hose. The idea here is NOT to create a lot of suds in the bucket - you really don't want any, in fact. And besides, it's not the suds that get the car clean, it's the emulsifiers, lubricants, etc in the soap that is dispersed in water that get the job done, not the suds. So, put the water in the bucket, add the rinseless wash product, stir it around with your hand, and start washing. Oh, having a grit guard in the bottom of the bucket is a good idea, too.

Start with the top of the car, washing a panel or smaller at a time. Immediately wipe the area dry with a waffle weave microfiber drying towel (if you're a huge fan of the Absorber, go ahead and use that), and then continue around the car section by section. D114 will release the accumulated dirt from your wash mitt pretty easily if you drag it over the top of the Grit Guard in the bottom of the bucket, and the crud that falls to the bottom of the bucket will stay there thanks to the Grit Guard. A couple of gallons of water should be all you need to clean a car this way, and you can clean a surprisingly dirty car very safely with this process.
