I had a windshield repaired on my jeep...cost was $30 and he came to my house to do it...took him 30 minutes and it was good as new...its since been hit by 3 more rocks and the original crack has not spread...although one of the rocks did have a run that ran all the way across the windshield...still broke to this day...but the one that was fixed is still holding...pay the $ to have the crack fixed...worry about the windshield the next time it happens...
