Diamon-Fusion is carried in over 3,500 car dealerships around the country and can be applied to your car windshield by professional applicators. For car windshield coatings that you can apply yourself, DFI offers Windshield Defender, which can be purchased on our e-commerce store at www.shopdfi.com. The coating can easily be applied to your car windshield, helping to repel water off the glass, thus improving visibility and driver reaction time.
