Thanks for the info. But it still puzzles me why a bead of water on a slick surface of a waxed car will not run off immediately when at an angle not exactly perpendicular to the ground. Is the surface just not really SMOOTH enough? Or is there enough adhesion on those beads to overcome the force of gravity if the incline is slight enough?
I normally use a leaf blower to dry off the car after washing it, and although Rejex (which I often use as my slicker-upper) seems to be pretty danged slick, those blasted beads will STILL resist that 200 mph air force I am applying to chase them away. And it seems that the smaller the bead of water, the more it resists just being blown off of the surface.
