    A windshield coating for microchips?

    Might there be something out there, that helps with the microchips a windshield in Colorado is subject to? All my vehicles that get driven a lot in this state, before long, have a ton of microchips from the sand and dust. So when the sun hits the windshield right, it becomes very difficult to see at times. And I know the best solution is a replacement, but this windshield is only 2 years old, and I`d rather wait until I get an actual crack again.

    So I`m hoping there might be something out there that helps with this? I know nothing will eliminate the problem entirely.

    A coating isn`t going to do much if anything, just too thin. There are a few film coatings on the market that look somewhat interesting.

    Unfortunately no. As stated PPF for glass is gaining in popularity.

    I`d love to read reports of those that have used PPF for glass. My head just says NO when it comes to windshield wipers but I`d like to read otherwise.

    I’ve seen cars with it before. It’s more clear than PPF but it’s still very noticeable, and the texture isn’t as smooth as glass.

    Optimum Opti-Glass coating was supposedly tested on a rental car fleet and reduced rock chips. Yes, I know that sounds impossible. I was just looking for the info over on the Optimum forum, but that may have been lost over there when Chris deleted all his posts.

    Scottwax mentions it in this thread in post #11: New Optimum Products and in post #10 in this one: Opti-Glass application video and long-term comparo vs Carpro Flyby30

    I don`t expect anything to prevent rock chips. They are large. I`m just hoping something can help lengthen the life of a windshield against the sandblasting. And any kind of coating that is hard enough, and reapplied periodically, could potentially do this.

    Nope. No coating is hard or thick enough. Look the PPF route others have mentioned.

    A lot of people think the 9h hardness is diamond hard due to this being sio2. Not how that rating works. It is 9h pencil hardness.

    “The pencil scale is a test of hardness that gives an impression on how hard a certain coating is. The test is done by pressing a pencil with a certain hardness firmly on the surface on a 45 degrees angle. The highest grade that does not make permanently mark the surface is the score for the pencil scale.”

    So if a 9h or even a 10h pencil can mark the coating with firm pressure, nothing is going to help against anything that is causing pitting in glass which is harder than any coating.
