Definitely, we recommend ceramic coating the exterior glass of your vehicle to prevent water spots, scratches and even dings from blowing sand or rocks. Ceramic on the glass usually lasts as long as ceramic coat for the paint and can be applied to your windshield, passenger side windows and rear windshield. It extends the life of your glass, improves your visibility and makes it easier to clean. Glass ceramic coating is another major advantage especially here in the desert of Phoenix with our harsh weather. If you’ve lived here for any amount of time, you know that windshield replacements are pretty routine. While ceramic coating can’t stop a rock from dinging your windshield at 65 mph while you’re driving down the freeway, it can protect against most other things Phoenix has to throw at it (literally).
