Just had a huge rock kick up and hit the windshield while on I-5, 70+ mph over the weekend. No damage.
Glad I had the coating applied just a week prior.
I don't work or get paid by dfi. It's just inexpensive insurance. Glad I have it and when I've parked it outside and the morning marine layer has left a layer of dew on the windshield a quick acceleration and it's gone. No windshield wiper streaks no water spots. I may do the top and rear windows just because of the hydrophobic properties.
Diamon-Fusion International
Scientifically Proven Safety Feature™
That sounds pretty complex, but what it really means is that you and your passengers are safer in a car that has a windshield (or windscreen) treated with Diamon-Fusion® than a windshield (or windscreen) with no protection, or even a competitor’s coating. It’s really that simple.
The Diamon-Fusion protective coating is a patented chemical invention that has been used by the US Army to provide better visibility and reduce the damage their HUMVEEs experience in the harsh environments in which they operate. In a passenger car or light truck, the windshield (or windscreen) is often part of the structural integrity of the vehicle so driving around with a chipped or cracked windshield (or windscreen) reduces the safety of the vehicle. The windshield (or windscreen) can actually help support the roof of the car and in some models it actually provides a backstop for the airbag.
Diamon-Fusion’s impact and scratch resistance was proven by tests conducted at the Institute for Glass Science and Engineering at Alfred University in New York. That test confirmed that to damage a surface treated with Diamon-Fusion, the force applied had to be ten-times more than what it takes to damage an unprotected surface. In other words, the smallest pebble that can do damage to your windshield (or windscreen), when traveling a certain speed and hitting a certain angle, has to be ten times larger to do damage to a Diamon-Fusion protected windshield (or windscreen)!
This damage-resistance, the increased reaction time provided by Diamon-Fusion’s hydrophobicity, the reduced night-time glare, the durability and longevity, and the overall increased safety of you and your passengers delivered by all of these benefits is why the US Army, the US Navy and over 750,000 vehicles have been protected with Diamon-Fusion around the world.
