To repair a windshield, resin is injected into the chipped area and holes can be drilled in the cracks to prevent them from spreading. Either way, it takes someone experienced to do the job, according to Popular Mechanics. Repair a damaged windshield as soon as possible. Sometimes the only answer is a complete replacement of the windshield.

Damage to the windshield perimeter increases the risk of total windshield failure in the event of an accident. If there are small gaps left after installing the windshield, the windshield will deteriorate quickly.
Another place where windshield repair should not be performed is within the driver's line of sight (the glass covered by the driver's windshield wiper).

You don't realize what's tied to that windshield in terms of technology until you need to replace it.
