Stone chips in a windshield can be repaired in most cases. As a rule of thumb, if you can cover the damaged area with a quarter, it should be repairable.
The repair process involves injecting a clear acrylic resin into the fracture. This bonds the glass back together and hides a large amount of the visible damage. It typically takes only 15-30 minutes and comes with a lifetime satisfaction guarantee.
Most insurance companies will reimburse you for the cost of windshield repair under the comprehensive portion of their coverage. This includes waiving any deductible.
