When rain accumulates in your line of sight, RainZip makes it bead up quickly and blow away, even at speeds as slow as 35 mph.
RainZip comes in a 3-ounce container, enough for two large windshield applications, each lasting three to four months. It also comes with special application cloths. MSRP is $30.95.
