There's a few routes actually. Rule of thumb is as water goes down microfiber towels goes up. Expect to need 10-20 depending on the process you're using. 300 gsm towels from The Rag Company or Microfiber Madness are great for this.
Ammo Frothe with a foamer is really good, just follow up with a quick detailer behind it.
ONR is another option and can be used as a waterless or rinseless wash.
Fold your towels into quarters. Work a single panel at a time, use straight lines, and roll your towel to keep the leading edge from building up too much grit and scratching the paint.
There's lots of great videos posted by detailers on how to, AMMO NYC and Pan The Organizer are on the short list to watch.
