Windshield Patch

Repairing a windshield using a windshield patch can be a do-it-yourself (DIY) project, and the patch is available in many DIY repair kits. However, using a windshield patch is rarely used by auto glass professionals because it is not the most effective solution to a cracked windshield problem.

To repair a cracked windshield with a patch, the first thing to do is to cut the patch down to size. Then, apply the patch over the area and smooth it out and give it time to cure.

The patch should harden and be able to straighten the affected area. Remember that the patch does not work its way down the crack or chip. It also does not strengthen the glass, but only help in keeping the glass together to prevent the crack from spreading.

Windshield Resin

According to the article, the most often used material in windshield glass repair is resin. Auto glass professionals rely on resin to fix chips or cracks. Repairing a damaged windshield with resin requires injecting resin into the crack or chip. Then, a heat source is used to allow the injected resin to heat up. As the resin heats up, it slightly expands and cover the chips and cracks to prevent a them from spreading and to strengthen the glass.
