if you happen to find a small chip in your windshield, don't worry. You don't have to go out and get your entire windshield replaced to retain its strength. Some small chips can be quickly and easily repaired with a windshield chip repair kit. Most automotive stores carry these kits for around $10 and allow you to inject resin into the trouble spot and remove excess air in the problem area. Once you've repaired the glass, you'll barely be able to notice your patch job.
