The wax is going to be affected by the weather, where you park it, how you're washing the truck and a lot of other factors imentioned in your other thread. Drying with a towel will always remove some if not all wax, but you'll know each time you wash by the sheeting and beading if wax is needed again. I wash 2-3 times a week by hand using the 2 bucket method and dry with waffle weave towels...I wax 1 a week with Adam's buttery wax. If I used a paste wax I'd only wax 1-2 a month, however I'm crazier about washing/detailing than most. If you enjoy it, do it often, if you don't...do it 1 a month or every other month.
