– Customer via Amazon

While some customers loved using the Permatex kit, others were unhappy with its tools and the quality of the resin.

“The kit boils down to being able to use this suction device with this metal spring. While the metal spring may look sturdy, it’s in no way connected and is much flimsier metal than a paperclip.”
– Customer via Amazon

What Is It Good For?

Before choosing your next auto glass repair kit, check out our buyer’s guide to learn more about how repair kits are designed to work and why they’re vital for protecting your windshield’s health.

What Is A Windshield Repair Kit?

A windshield repair kit uses epoxy resin to fill in cracks and seal them. They work best on minor damage such as chips, bullseyes, and stars that are less than one inch in diameter.

You should repair a damaged windshield as soon as possible. Not only is a windshield replacement very expensive, but a damaged windshield can compromise visibility, putting both yourself and other drivers at risk of an accident. Road grime can work itself into a fracture and prevent epoxy from properly fixing the issue. Temperature changes can also cause a crack to expand and fracture further.

Cleaning your windshield is also essential to keeping it in pristine condition. Whether you’re looking for the best auto glass cleaners or the best windshield wipers, there are a lot of great options to consider.

Our Review Standards

To select the five windshield repair kits in this review, our team searched Amazon and Advance Auto Parts for top products, looking at factors like customer ratings, price, superlatives, and Prime shipping eligibility.

Can I use my windshield repair kit to fix a broken window on my car?

Generally, windshield crack repair kits are specifically designed to fix the laminated glass of a windshield. You must check your vehicle’s manual to learn what type of glass it is before trying to repair it with a windshield kit.
