Here's a little trick I heard about. My father-in-law used to race Trans-Am series cars. In one race they had a downpour and he noticed some of the other, more experienced racers would rub tobacco all over their windshield. Has anyone else ever heard of this? Might work well in a pinch. I don't know how may of you carry a spare potato in your truck, but I would imagine at least a few of you have a pack of cigarettes or two within reach. Hey, maybe I just solved Phillip-Morris's dilemma!!
