My car doesn't dry after it rains?

Let me try to explain:



I've currently been waxing my car with either S100 or Natty's Blue. They've both produced excellent results and good beading--which seems to be the problem. Everytime it rains, the droplets seem to sit there and hold place for an entire day. Sometimes I've woken up in the morning after a heavy rainshower the night before, and there would be areas of the car still full of water beads, while all of my neighbors' cars have completely dried. The result is usually water spotting unless I am able to dry the water off before.



I've always been under the impression that water beading was good, but I've never completely understood why. What is supposed to be the benefit? Is there a type of product that helps sheet water off paint like Rain-X does on windows?



I certainly won't stop waxing but I'm curious to know why the wax appears to create a 'delayed effect' on my car drying. Or if it's even that and not something else...



I also really need to get myself a garage. :scared:
 
As to your question about beading being good....it's not really good as far as water spotting, and the reason your car takes longer to dry is that the largely spherical shape of a bead has a very large volume-to-surface area relative to water that sheets out on the surface (smaller exposed surface area means slower evaporation). Everybody likes beads because it's tangible evidence that your car has wax protection on it, they look cool, and it's entertaining when they run off.
