Stone chips occur when you drive on a dirt road or on a road with gravel. When a car drives in front of you, it shoots stones at your hood with its rear wheels. Depending on the speed and how they hit your car, the gravel can cause starbursts in your windscreen and pits in your hood.
This is of course not pretty. Especially on the windscreen, you do not want any distractions. To prevent stone chips on your windscreen or hood, you can use a stone chip cover. These covers are made of skai. The covers are custom-made for different car models, you can easily find the right one for your car with your licence plate. The skai is soft on the inside and prevents scratches and stone chips. If you are going to drive on unpaved roads, you can easily clamp the cover around your hood.
