I have used the autodry system for well over a year. I have the original version, not the "professional" version. I only use the autodry applicator to spray the filtered water-the final step. I do not use the autodry applicator to spray soap or to rinse off soap. Instead, I use a foam gun filled with the autodry soap and spray the autodry soap into a boar's hair brush, wash one section at a time, then thoroughly rinse out my brush. I use another nozzle to rinse off the soap. I use but don't really care for the autodry soap as it seems to leaves a residue on my brush. However, the product works as advertised. Many contributors to this site dedicate considerable time to washing techniques designed to avoid paint finish damage. The real beauty of this product is that you avoid touching your vehicle during the drying cycle. Just as much or more paint finish damage can occur while drying as occurs while washing. With autodry, no water blades or MF towels come in contact with the paint finish. I also think it is a real time saver. Conventional drying methods are far more time consuming than washing. With autodry, washing and drying take about the same amount of time. It's worth a try.
