I did my own,, there is a windsheld chip repair kit for about $10.00 it has a stickie thing you put over the chip/crack/star crack rub it good you don't want any leake then you screw a seringe pump ,,put as much pressure as you can it will fill all the little cracks ,,,afterwords you can't see where the chip was, unless it was a hole not just cracked. jim
