I was told about this new product today. Pretty amazing video showing the stuff in action. As I was watching it, I was wondering if air flow would be improved any somehow. If anything, sprayed under a car, you wouldn't have mud or maybe even slush sticking to the underside, thus adding extra weight. If it repels slush and snow, THAT ALONE may be VERY helpful!!

If anything, it's a COOL product FOR SURE!!!
