Just discovered my wife's car has a crack running from the passenger side top edge, to what looks like a rock impact point.. then from there it's making a run for the passenger side edge of the windshield... go figure that the car that has the crack is the one with only liability insurance on it (it's '91 with almost 165k miles on it.. and a second car.. if it goes, it goes.. we'll move on) i've seen the DIY repair kits for these things.. any opinions on which are the best? and where to find them?
