Nasiol Glass Shield is a high-performance spray-on glass coating designed to dramatically improve visibility and driving safety by repelling water, snow, and road grime from your vehicle's exterior glass. Perfect for rain-prone and winter climates, Glass Shield bonds instantly to glass surfaces and reduces the need for wipers.

Key Features & Benefits

🔹 Exceptional Water Repellency – Creates a strong hydrophobic barrier that turns water into beads and sweeps it off the windshield effortlessly.
🔹 All-Season Glass Protection – Helps delay ice buildup in winter and shields glass from dirt, bugs, and road spray year-round.
🔹 Improves Driver Safety – Enhances visibility during rain and snow, especially at highway speeds.
🔹 Long-Lasting Performance – Protects glass for up to 2 years or 80,000 wiper passes with just one application.

How to Use

Step 1: Thoroughly clean the glass using a glass-safe cleaner or Nasiol Clean to remove any residue. Dry completely with a lint-free microfiber towel.
Step 2: Shake GlasShield bottle well. Wear included nitrile gloves before application.
Step 3: Spray directly onto the glass (approx. 20 sprays per 1m²) and spread using the included Nasiol cotton cloth (do not use microfiber).
Step 4: Buff immediately and evenly for full coverage.
Step 5: Let the surface cure in a dust- and water-free environment for at least 24 hours.

Pro Tip: Avoid applying in direct sunlight or to hot surfaces. Always treat cool glass for best performance and streak-free results.
