How Do I Fix a Chipped Windshield

Wondering how do I fix a chipped windshield? You can make this repair yourself easily, but you will still be able to see a flaw in the windshield at the repaired spot. The repair will keep the windshield from cracking further, so you won't need to replace it.

Before you start your repairs, be sure to check the windshield insurance provisions in your vehicle insurance policy. You may be able to get your windshield replaced, or have a professional repair the chip, at no cost.

Windshield Repair Kits
Repair kits can be purchased at most big-box auto supply stores. Most of these repair kits will not fix a crack that is larger than 1 1/4 inches. If you see different brands of repair kits, read the instructions on each one to make sure you purchase something that will work for the crack or chip in your windshield. Some repair kits will only work on very tiny chips.

Making the Repair
Move the vehicle into the shade. The hot sun hardens the resin too fast, and the repair will not look right. Once the vehicle is in the shade, clean the damaged area of the windshield. Use a razor blade to remove any loose pieces of chipped glass. After all the glass is removed, clean at least a six-inch area around the crack or chip. Use a good glass cleaner or denatured alcohol. Make sure the windshield is completely dry before continuing.

The repair kit includes a suction cup tool. Center the threaded section of the tool directly over the damaged area. Press the suction cups onto the windshield. The tool is adjustable, so once the suction cups are stuck on, you can adjust the arms so that the threaded part is directly over the damaged area. Look at the alignment of the tool from the inside of the vehicle to double check that it is properly aligned with the damaged area. If it is not aligned properly, remove the tool and realign it.

Open the tube of resin. Put two to four drops, according to the instructions on the package, into the tool. Insert the plunger and tighten it so that it is almost all the way down. Once it has been tightened, loosen the plunger a bit so that air bubbles can escape. Tighten the plunger again. If you do not allow the air bubbles to release, they will stay in the resin, and the repair job will not look nice.

Allow the resin to seep into the crack for at least 60 seconds, or for the amount of time specified on the package. Remove the tool. Lay a piece of the clear finishing film from the repair kit over the repair area. The area should still be moist when you apply the finishing film. Press the resin toward the edges of the film, using a razor blade to spread the resin.

Let the resin dry under the film. Make sure the resin is not wet when you pull the film off the repair. It should set for at least 10 minutes, but if you are doing this on a cool day, or a day with high humidity, it may take longer to dry.

After the film has been removed, scrape any excess resin from the windshield with a razor blade. If the crack or chip is still highly visible, repeat the process. Deeper chips or cracks may need two or three layers of repair. Don't try to do it all in one pass, as the resin will not dry properly.
