I just bought this do it yourself windshield repair kit that fixes cracks, chips, bulls eyes, and stars. I have a star in my windshield from where a rock hit and I want to get it fixed before it spreads like what happened to my dads car. I was wondering if anyone has ever tried fix a windshield? And if it needs to cure in direct sunlight? I read the instructions on the back and it doens't say, I have to open it to read more detailed ones. Please reply.
