Door sills seal the bottom portion of the vehicle by filling the gap between the door and the car floor. They protect the interior from unwanted dust and particles. With constant entering and exiting from the vehicle, the door sills may be damaged. Continuous opening and closing of the door may damage the paint or create scratches. You can purchase door sill protectors to keep the area looking nice. Door sill protectors come in a range of different materials to allow you to match your existing vehicle or be statement pieces. They fit over the existing sills to provide protection from wear and tear. You can also replace existing door sills if you find they are completely worn out and need a refresh.
