I've been using ONR wash & wax for the last several months and very pleased with the results. My method is using 5 microfiber towels, using one at a time folded in quarters and splaying a clean side after 1-2 passes. Generally only use 4 sides of a single towel before reaching for a clean one. After cleaning a panel or section of panels I use a microfiber towel to dry, and have two towels switching to a new one after 1/2 the car is done.
Edit: If the car is real dirty I will pressure wash off the heavy stuff first.
