Windshields are susceptible to damage from rocks and other debris while driving, and every driver will experience a crack or chip at some point. Once a crack appears it will usually spread, and then it’s game over. With a windshield repair kit, you can fill chips with a resin-based sealant, which might keep the damage from spreading. Here are the best windshield repair kits available on Amazon.

How to use a windshield repair kit
Using a windshield repair kit is relatively easy, and most of them work the same way. First off, make sure your car is parked outside and you know where the damage is located. Next, use a thumbtack to clean out any loose glass in the crack and wipe down the surface with the cleaning pad. Next, apply the resin fill into the crack or chip and place the curing film on top of it. Let it dry for the recommended amount of time according to your kit’s instructions then remove it. To finish things up, scrape off excess resin residue from the area with a razor blade.
Are there any downsides to these repair kits?
A major downside to consider is that they can only cover bullseye cracks up to a certain size. They are unable to cover more significant damage such as spiderweb cracks, starburst chips and long windshield cracks. Another disadvantage they face is if the crack isn’t attended to fast enough, it will likely grow and expand and lead to the entire windshield needing to be replaced. These kits are a bit of a Hail Mary: They will not remove the damage, but they might stop it from spreading and make it less noticable.
Should I repair windshield damage immediately after it happens?
Once your windshield is damaged, it’s best to act on it as soon as possible. A crack will likely spread.
What if the crack spreads?
A cracked windshield is a safety issue. Contact your insurance company. Covering replacement windshields is a big part of what they do.
Can I use a windshield repair kit on other windows in my car?
You can use it for small chips and cracks on other windows on some occasions, but it’s rare for them to be chipped while driving.
