The repair will only be on the vehicle with the code and is not transferable to another vehicle. We provide one complementary chip repair during the first 12 month after your windshield replacement. Please note that if the chip can not be repair, we will not provide a new windshield. A rock chip repair is not a cosmetic repair; you may still see where the chip is located once the repair is complete. After the completed repair you have a lifetime warranty that the chip will not spread from the original repair location. It is important to know the appearance after a windshield is repaired is not an indicator of whether or not the repair was successful. Since we are working with a glass that is already broken, during the repair, there is always a possibility that as the technician is pushing the resin (glue) into the chip that the chip could spread.
