I've tried compressed air but I need a filter to pull out the moisture since it takes so long. I have waffle weave towels, they do "ok" but I think the best is one of them synthetic shammy things and wax as you dry. Problem is any towel method leaves water behind badging, trim, mirrors and so on. I'm seriously looking into a CR system since I can rinse in my garage, dry by shammy/towel and blow out the emblems and such.
