When your vehicle’s windshield is damaged, you typically have two options—to either repair or replace the glass. If a crack is shorter than six inches or a chip is smaller than the diameter of a quarter and is not in a "critical focus area" (in the driver’s line of vision), it is probably a good candidate for repair. Repairing damaged glass involves a process by which a heated resin is injected into holes and cracks. If you choose to repair the glass, your deductible is waived and you incur no out-of-pocket costs. There is no risk, since most insurance companies guarantees the repair.
