Over the cold weekend, a small crack has formed on my windshield from the edge moving it's way towards the center. It's a couple inches long, so not very big at all and completely smooth to the touch. So I'm guessing it's weather related since there's no chips or anything you can feel. Anyhoo, I was wondering if you guys had any suggestions on stopping it from spreading? I don't mind going to a professional shop to get it "stopped" but I don't want to pay them and have it still spreading anyways, so if anyone had experience with this method then that would be reassuring before I did it.
