I am considering buying a CR Spotless system. I don't have the option of working under shades most of the time and in Florida the the sun or heat will dry car too fast. I don't have a shop so I am mobile. 1. Will I have to do the entire wash or just the final rinse using the cr? 2. I have a pressure washer and water tank. If only the final rinse must be done using CR - what is the most effective way to set up my CR system? 3. Any pics of your set up - if you have a mobile unit will be appreciated...
