Listen, I'm 25, and I can sit here and argue all day long with you if you wish. I usually don't do much during the day anyways. I'm just choosing to stop with this nonsense.
Wax provides a barrier. If it didn't, dirt and grime wouldn't spray off so easily when I spray it with water. I've had vehicles that did not have any wax or other protection applied and the dirt stuck like glue.
