For older or higher mileage vehicles, for best results it is recommended that the Nanovations Deep Glass Cleaner be used prior to the application of Vision Protect. A clay bar may also be used to deep clean the glass prior to treatment. Do this if the following conditions exist
- Windshield has been treated with another Hydrophobic coating.
- Vehicle is three years or older or has 30,000 miles plus on odometer.
