I'm looking to begin a no wipe exterior wash. Is a RO spot free rinse system a must? If I am getting dry cars with the blowers do I need to worry about spotting? Also if I add the spot free rinse would that mean that I don't need to worry about getting the car as dry? In other words do I invest in additional dryers or invest in the spot free rinse or do I need both?
Thanks
Paul
