It's a windshield treatment, wipe on. Reduces surface tension. At\r\nhighway speeds (well, highway speeds other than in LA), the rain just\r\nbeads and is swept off your windshield in the slipstream. The effect's\r\npretty good above 30-35 MPH even, so you can get by in a pinch. Even\r\nstanding still, rain tends to glide off rather than stick, so you can\r\nsee out.
\r\n\r\nThe wipers on my truck ('91 Toyota Xtra Cab) have a tendency to lose\r\nadhesion to the windshield at 60+ MPH, so this actually gives me better\r\nresults than blades. Highly recommended.
