A vehicle sensor system is described comprising an exterior surface; and a repellent composition disposed on the exterior surface, wherein the repellent composition exhibits an increase in haze according to the Dirty Water Spray Test of less than 5, 4, 3, or 2%. In typical embodiments, the repellent composition exhibits an advancing water contact angle from 90° to 125°. In some embodiments, the sensor system comprises a camera, a laser, a LIDAR sensor, a sonar sensor, or a radar sensor. The exterior surface is typically a windshield surface, a protective housing, or a lens surface. In some favored embodiments, the repellent composition exhibits a roll-off angle of no greater than 25, 20, 15, 10 or 5 degrees. Also described is a protective film, a repellent composition, a coating composition, and a method of evaluating repellency
