If you’re anything like me, then you know how much it sucks if you’ve broken or cracked your windshield. It’s frustrating, expensive, and can be a pain to fix!

Sometimes glass cracks happen for no apparent reason and can be caused by something as simple as a rock, stone or pebble in the road, a bird strike, or even bumping into another vehicle at a congested traffic light.

Sometimes it happens while driving on the freeway and a piece of debris from a truck gets kicked up and flies into your windshield. Sometimes one tiny chip will quickly turn into a huge mirage-like spider web. And sometimes a chip will happen right by a strong gust of wind or a big raindrop.

Whatever caused it, if you’ve had a piece of debris, bird, or even a vehicle chip your windshield, you’ll want to fix it before it gets worse.

So here they are, the 10 best windshield repair kits of 2019!

Some of them contain a little bit more packaging than others but each one should do the trick in fixing up your glass.

Frequently Asked Questions (FAQ)

Which windshield repair kit is the best?

We've concluded that, hands down, the best windshield repair kit for the money is the GEBAOFENG Windshield Repair Kit. Its uniquely designed bottle allows for greater control ensuring you only get the filler in the crack when you squeeze. This is a much better design than some of the competitors, which can get filler on your hands or the paint on the car. This is also a great kit because it comes with a UV indicator, which is critical if it's going to sit in the sun for more than a few days. It will only work if the part is cooled in a refrigerator.

Other manufacturers don't provide this UV indicator. While this is not critical for the longevity of the repair, it is helpful in insuring your repair is lasting longer than a week.

Do windshield repair kits really work?

Yes they really do work, but they don't fix your problem by themselves. You'll need to have some skill and know how to do the repairs. Professional body shops or Ma and Pa shops will never use windscreen repair kits. They simply cannot provide the quality of work that your car or truck deserves.

For the do it your selfer, the windshield repair kits are not that difficult. In fact, the Auto Glass Experts have a pdf download that describes the method using one of their kits. Just click on the link above to see it. It is really a pretty easy process. But you must be sure you are doing it correctly.

The Wiper’s Choice with Teflon Safety Seal Windshield Repair Kit is a great windshield repair kit, although we have found that it's made by a number of different companies (some of which we will mention below). This kit features a repair disc and an accelerator compound.

What is the best windshield brand?

The absolute best windshield brand is PPG. They make original equipment glass for both domestic and import cars. They have an outstanding reputation for both glass quality and service standards.

PPG is the windshield vendor of choice for most of the world’s auto manufacturers. When considering the windshield brand, it’s important to look beyond the labeling. A replacement windshield is typically marked with the name of the glass company, but these days it’s becoming more and more common to see generic labels on windshields. This is typically a sign that the replacement is actually made by the OEM.

Michelin is the second largest glass supplier in the world. They primarily operate in Japan, Latin America, the Middle East, and China. They also make European replacement glass for several manufacturers, and are the main windshield supplier for the Volvo brand. Here in North America, they are also a major OEM supplier.

Do it yourself fix cracked windshield?

Yes a windshield repair is a pretty simple job that is not that difficult to accomplish. Here’s a quick rundown of the procedure if you have never attempted it.

Use the spatula tool to spread an even line of adhesive about 3/8" in from the crack. Cut the glass fiber mat to a size approx. 1-1/8" to 2" larger than the repair area. Place the glass mat onto the adhesive wait for it to stick to it, press firmly on the mat. Hold the spatula tool across the top of the mat and roll it towards yourself using a smooth rolling motion. It is best to hold the glass fibers down with your thumb, and roll with the rest of your fingers. Wipe away any remaining adhesive.

So with this as an introduction, you can do your own windshield repair. However, if you are going to try it, here are a few things to keep in mind.

Conclusion

When you take a close look around your vehicle, you’re probably going to see that windshields are only one part of the vehicle that can be damaged. It may not be a big surprise to anyone that damage can occur from a number of different sources. Rocks can hit it, eyes can look at it (but not while driving of course!), and a number of other reasons why you could come out from your car to discover your windshield damaged. Luckily there is a good chance there is an easy fix.
