SharpShield Liquid Glass Protection - Be Road Safe

Wet weather, glare, pitted windshields, and darkness all compromise vision while driving. In the United States alone, there are over a million wrecks each year caused by poor visibility. On top of this, small rocks and road debris cause chips and cracks in windshields which can lead to high repair costs, or even worse, put the occupants of your vehicle safety at risk. SharpShield liquid glass protection will help you be more road safe when you drive.

SharpShield™ uses nano-chemistry to  reduce these concerns by addressing the underlying cause of many of these visibility issues: the physical structure of the automotive glass itself.

SharpShield resists glass pitting

How Does SharpShield ™ Work?

Did you know vehicle glass is not smooth? In fact, when viewed under a microscope, ridges and valleys are present in the surface of the glass. SharpShield ™ bonds to the glass to fill in the ridges, adding up to 40% greater strength that lasts up to four years with no re-application.

  • Strengthens windshield and windows by up to 40%
  • Repels rain, snow, dirt, ice and makes them easier to remove.
  • Increases nighttime vision up to 35% while reducing glare.
  • Long lasting formula bonds to glass for up to 4 years.
  • Resists scratching and pitting.
  • Non-toxic and environmentally friendly.

Common SharpShield Questions

SharpShield is a polymer suspended in water. When applied to glass, SharpShield will chemically bond to the silica in glass and turn to solid form when the water carrier evaporates. Windshield glass has many imperfections that can only be seen microscopically. The chemical bond increases the surface integrity of the glass by filling in the imperfections.

SharpShield is formulated to bond to silica in glass and is not affected by detergents, wiper blades or minor abrasion. This makes the bond last up to 4 years.

SharpShield is not guaranteed to stop all rock chips that could potentially break the windshield, but will reduce the chances of a break. Testing indicates 20 to 25% added surface strength with one coat of SharpShield, and up to 40% with two coats.

Headlights and streetlights refract light off of the imperfections in the windshield creating a “halo” effect and glare. SharpShield minimizes the imperfections which reduces the glare up to 35%.

Not at all. Most repellent items do only that, repel. SharpShield, while being very repellent, also strengthens glass and improves nighttime visibility in any weather, not just rain and snow. Additionally, these products are made from silicone that sit on top of glass and does not bond to it. They are susceptible to detergents, wiper blades, and weather requiring reapplication.

Both. Putting SharpShield on a new windshield before any damage can occur is always best. Although SharpShield will not fix existing damage, it will minimize risk of further damage and pitting.

Most insurance pays for only small cracks or chip repair, or has high deductibles with windshield replacement. Most do not cover costs of a new windshield. Many new vehicles require more difficult replacement due to electronics attached to the windshield and the need for calibration.
