Rain-X Water Repellant Liquid 3.5 oz | Stine Home + Yard : The Family You Can Build Around™

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 safety and driving comfort response time up to a full second or more. At highway speeds, that’s almost four car lengths of extra stopping distance.
