Between spring and autumn, the vehicle is mainly exposed to water, so the water repellency of surfaces is important for safe driving. Add insects, pollen and road fat, and it often happens that looking trough windscreen is almost impossible in the rain. Bird excrement, air rust and physical damage (scratches, hail, …) are especially harmful to the body. Regular cleaning of the vehicle during this part of the year is necessary, but the frequency and aggressiveness of cleaners can be greatly reduced if the surface of the vehicle is adequately protected.
