Cracks, chips and bull's-eyes are all common imperfections that devastate windshields and can make it unsafe to drive. Imperfections usually result when the windshield hits a hard object at high speeds. This doesn't always mean your windshield must be replaced. Many imperfections can be repaired easily with auto glass repair kits, which are widely available at auto part stores.

Before you start

We've all been there: you're driving along, minding your own business, when suddenly—CRACK. You look up to see that your windshield has been struck by a rock, or maybe a flying bird. If you're lucky, it's not too bad—maybe just a chip or crack. But if the damage is too big to ignore, we have some tips for making sure your repair goes smoothly and lasts for years to come.

Before you start:

-Whether you’re fixing a chipped or cracked windshield, make the repair in the shade. Expose it to direct sunlight after the repair is complete so that the resin can cure. For best results, make the repair soon after the damage occurs and before the break can be contaminated by dirt and water.

Repairing chips: Step-by-step instructions

1. Clean the windshield with a dry towel.

2. Center the ring of the applicator base over the impact point of the break.

3. Screw in the resin chamber until it touches the impact point of the break.

4. Carefully squeeze resin into the resin chamber.

5. Unscrew and remove the pressure driver, then re-insert it into the resin chamber to drive out any air remaining in the break.

6. Remove both pieces from your windshield and touch up if necessary (sometimes you can do this while you're waiting for your resin to cure).

7. Apply curing strips on both sides of the crack, exposing them to direct sunlight for five to ten minutes before removing them (this will harden your resin). 8. Scrape off any excess resin before driving away.
