I don’t use the 2 bucket system, Pressure wash to knock off the dirt, use Tri-Nova shampoo & conditioner with the foam gun, quick once over with the microfiber glove and rinse. Good as new. Highly recommend Chem Guys waffle towel as it soaks up the water in one swipe. A year later with 19,000 miles and she still looks brand new. Also recommend a paint correction once a year for those that do not have any protection on the paint.
