I had a rock or something hit my front windshield last week that left a dime sized crack. I got it fixed today with pretty good results. Attached is a before and after picture. I can not even find the crack from the outside and it is bearly noticable from the inside after the fix. They came out to my house and it took less than 30 minutes. Best of all, it was free to me because my insurance pays the deductible and the structural integrity of my windshield has been restored.
