Few things can make you more furious than a rock flying up and chipping your windshield. Not only does it make your car look janky, but it can also impact your visibility and be a safety hazard.
You have a handful of options to fix it: You can get a new windshield, which will cost you an arm and a leg, you could use the services of a professional glass repair company, which would cost you half a kidney, or you could use a DIY windshield repair kit.
But do these kits even work or are they just a scam? Your success in using a DIY windshield repair kit will depend on a few factors, but they aren’t a miracle solution and won’t completely erase a crack or chip.
A kit will work to some extent, fixing or stopping the damage from getting worse. Realistically, they will not fully remove the rock chip or the crack, but a good DIY kit will stop the crack from expanding and save your windshield from further damage while hiding the damage from plain sight.
A chip or a crack in the windshield can increase in size if left unattended. This can pose a safety risk and also reduce the driver’s visibility. DIY windshield repair kits will fix the aesthetic appearance of your windshield while providing safety from further damage. A good kit will hide the damage and one will have to look really hard to even notice it. Some windshield damage will certainly require the expertise of a professional, but a DIY kit can, in most cases of small cracks and rock chips, save you a good amount of money.
There are dozens of DIY windshield repair kits in the market right now, but we’ve gone through all the reviews and ratings and narrowed it down. The one common element between most of the kits is the resin solution that comes with it. It helps fill the crack/chipped area and strengthens the surrounding area of the glass.
