Windscreen Protection & Glass Coatings
FAQ's: Windscreen Protection & Glass Coatings
-
A ceramic glass coating is a liquid product designed to bond with your vehicle’s glass surfaces and create a slick, protective layer. This invisible coating repels water, dirt and road grime, making your windscreen and windows easier to clean and improving visibility during rain. A proper glass ceramic coating also offers resistance to chemical etching and water spotting, helping to maintain the clarity of your car's windscreen over time. Unlike standard glass cleaners or rain repellents, a ceramic glass coating chemically bonds to the surface for longer-lasting protection. It works by forming a hydrophobic layer that causes water to bead up and roll off the glass, reducing the need for wipers and improving overall safety when driving in wet conditions.

The main difference lies in durability and application. A glass ceramic coating typically offers longer-term protection and bonds more strongly to the surface, requiring slightly more preparation and curing time. These are often marketed as windscreen ceramic coatings or professional-grade solutions designed for those who want extended hydrophobic performance. A glass spray coating is generally easier to apply, often as simple as spray on, wipe off. While it also boosts water repellency and surface slickness, it doesn’t last as long as a full ceramic coating. Spray coatings are ideal for topping up an existing windshield coating or for drivers looking for a quick and easy maintenance solution.

Surface prep is essential for getting the most out of any car windscreen coating. Start by giving the glass a thorough clean using a glass-specific cleaner to remove fingerprints, dust and surface grime. If the surface has water spots, road film or other contaminants, consider using a glass polish or dedicated water spot remover to ensure the surface is fully decontaminated. After cleaning, we recommend using an isopropyl alcohol (IPA) wipe or panel prep spray to remove any remaining oils or residues. This ensures the glass coating bonds directly to the glass itself and not to leftover products. Whether you're applying a spray-on ceramic coating or a more durable windscreen coating, clean prep equals better durability and better results.

The lifespan of a glass coating depends on the type of product and how the vehicle is maintained. A full ceramic glass coating can last anywhere from 6 to 12 months, sometimes longer with proper prep and maintenance. These coatings are built to resist weather, wiper abrasion and contaminants, offering long-lasting performance on your car’s windscreen and other glass surfaces. Spray-on glass coatings, while easier to use, tend to last for 1 to 3 months and are best suited as maintenance toppers. You can extend the life of any windscreen coating by regularly washing your glass with pH-neutral products and avoiding aggressive cleaners that strip protection. Regularly topping up with a compatible spray can help maintain that crisp, water-repelling performance.
