Rain-X Original Glass Water Repellent : dramatically improves wet weather driving visibility. Simply apply the treatment to exterior glass and watch the raindrops fly off your windshield while driving. Rain-X helps improve visibility by repelling rain, sleet and snow. In tests conducted by a major university, better visibility improved driving response time up to a full second or more. At highway speeds, that’s almost four car lengths of extra stopping distance!
