With the help of a water-repellent spray, you give your car a transparent protective layer that repels water. Water will simply bead up on the surface of your car and roll off. This not only looks fantastic but is also very useful for the car paintwork. During heavy rain, water will slide off the car paint much faster. As a result, your car will be dry faster and dirt particles will be less likely to stick to the raindrops on the car paint. So your car will stay clean much longer. Discover below all water-repellent sprays for car paint, glass and plastic.
