Best Windshield Repair Kits of 2022 (Reviews & Buying Guide)

Few things can make you more furious than a rock flying up and chipping your windshield. Not only does it make your car look janky, but it can also impact your visibility and be a safety hazard.

You have a handful of options to fix it: You can get a new windshield, which will cost you an arm and a leg, you could use the services of a professional glass repair company, which would cost you half a kidney, or you could use a DIY windshield repair kit.

But do these kits even work or are they just a scam? Your success in using a DIY windshield repair kit will depend on a few factors, but they aren’t a miracle solution and won’t completely erase a crack or chip.

A kit will work to some extent, fixing or stopping the damage from getting worse. Realistically, they will not fully remove the rock chip or the crack, but a good DIY kit will stop the crack from expanding and save your windshield from further damage while hiding the damage from plain sight.

A chip or a crack in the windshield can increase in size if left unattended. This can pose a safety risk and also reduce the driver’s visibility. DIY windshield repair kits will fix the aesthetic appearance of your windshield while providing safety from further damage. A good kit will hide the damage and one will have to look really hard to even notice it. Some windshield damage will certainly require the expertise of a professional, but a DIY kit can, in most cases of small cracks and rock chips, save you a good amount of money.

There are dozens of DIY windshield repair kits in the market right now, but we’ve gone through all the reviews and ratings and narrowed it down. The one common element between most of the kits is the resin solution that comes with it. It helps fill the crack/chipped area and strengthens the surrounding area of the glass.

How to repair a chip or crack in your windshield

Our cars are tough machines, but even the toughest vehicles can’t compete with a small object flying right into your windshield.

If you drive a lot or far enough, it’s bound to happen. The good news is that many types of windshield cracks and scratches can be fixed, without costing you too much money.

This is what you should do.

01. Act fast!

If you want to get the best results, you have to hurry. Ideally, you’ll want to have your windshield repaired within a few hours of the chip forming. This will allow the repair kit to be more effective at removing air and debris from the chip, and will not allow cracks to form and spread through the windshield.

And if you think chips and cracks aren’t worth the time or effort for repairs, keep in mind that your windshield provides 45% of the structural integrity of your vehicle’s cabin in a frontal collision and 60% in a rear collision. rollover So yes, it’s worth it.

Note: Repairing chips or cracks that are directly in the driver’s line of sight is not recommended. Even the mildest windshield repairs will distort the glass and can damage your vision.

02. Identify the chip or chip

The ease of repair and overall results will depend not only on the size of the blemish, but also on whether it is a chip or a crack.

A splinter indicates the point of impact where the windshield was struck: this is the circular formation that appears. A crack is any type of line that extends from the original point of impact.

Your results will depend on three main factors: size, depth, and location. In general, the splinters are where you will have the most luck. Any chip smaller than a quarter will be easy to repair, and touch-ups to chips up to 3 inches wide should be at least moderately effective.

Cracks are a bit more complicated. A crack shorter than 3 inches should be manageable, but you will have more difficulty with cracks that range from 3 to 14 inches. Any cracks that go any further, especially if they extend to the outer edge of the windshield, might not be worth trying to fix.

Keep in mind that there are different types of chips and cracks: star breaks, bull’s eyes, craters, horseshoes, spider cracks, flowers, grooves and more.

03. Clean your windshield

Since your goal here is to return the windshield to its purest, cleanest state, make sure there is no dirt or glass debris in the area of ​​the chip.

Start by using a straight pin, safety pin, or similar object and gently scrape any glass or debris from the splinter area. Next, you’ll want to clean the area of ​​the chips, but make sure you don’t use detergent or window cleaner; use a microfiber cloth and spray it with rubbing alcohol, or even a small amount of lighter fluid or acetone, then wipe the area clean. Make sure to pour the liquid onto the fabric, not directly onto the glass.

You’ll want to make sure your windshield is dry and clean before you begin. Use a hair dryer if you need to dry your windshield quickly. Ideally, you’ll want your windshield to be at room temperature.

04. Follow the instructions of your kit

Repairing chips and cracks in your windshield isn’t that easy that household items will suffice. Fortunately, there are plenty of windshield repair kits on the market, and a good one will usually set you back $10 to $20 US.

The most common type of windshield repair kit is a few pieces. Essentially, it will include two main components: an adhesive patch that can be applied to the area of ​​the chip or crack, and a syringe that will suck air out of the damaged area and pump the adhesive onto the chip.

Since the intricacies of these kits will vary, it’s always best to follow the instructions once you have the kit.

Do windshield repair kits really work?

Q: Do windshield repair kits really work? A: Yes. As long as the windshield damage isn’t too extensive and you properly follow the instructions, you can successfully repair a crack or chip. However, it may still be visible; not all repairs are undetectable.

How big of a crack in the windshield can be fixed?

The rule of thumb: If you have chips larger than a quarter or cracks longer than 3.5 inches, plan to get a new windshield. Take note that even smaller cracks and chips that are extremely deep may not be fixable!
