6 Best Car Windshield Repair Kits for Various Types of Windshield Damage

A small crack or a chip on the windshield is every car owner’s nightmare. No matter how small the chip, it will eventually lead to a full-blown crack if left untreated. Driving with a cracked windshield is not only dangerous, but you also run the risk of getting a ticket. So, it is best to take immediate action once any sign of crack is visible.

Cracks of more than an inch usually require total windshield replacement, which is very costly. But if it is only a minor chip, less than an inch, you can do away with the expensive replacement. A DIY (do-it-yourself) car windshield repair kit can offer a solution by allowing you to fix the cracks for a small price.

There are a lot of different repair kits on the market, and while there is no perfect product that fits all purposes, if you know what the difference is, you can decide which one is the best for you. 

In this article, you will find my recommendations of the top six kits, and explanations when to use which. In a hurry? My top six kits are:

Keep in mind, these windshield repair kits are not miracle solutions for all types of cracks. There are certain damages beyond the scope of these DIY windshield crack repair kits, for which a glass replacement is the only solution. 

Thus, before considering using a DIY cracked glass repair kit to fix the windshield damage, it would be best to understand the different types of glass damages.

Types of Windshield Damage

Types of Windshield Damage

Not all windshield cracks are the same. Here is a run down of the most common types of damage. And for a little more information take a look at our article on windshield crack types.

The Bullseye

A bullseye is a type of windshield damage that occurs due to a flying rock causing an impact to the glass, resulting in a crack resembling a spider web or a dart board’s bullseye. The bullseye is a common damage to the windshield that is easily repairable, depending on the extent and location.

While a bullseye crack is generally small, it may develop into a bigger crack if left untreated, requiring complete windshield replacement. So, don’t take a bullseye for granted. Once it is visible on your car’s windshield, be sure to make the necessary repairs to minimize the cost and avoid an expensive replacement.

The Chips

A chip is a minor damage to the windshield due to the impact of a small flying object, like a tiny rock or pebble. But at high speed, the impact can be strong, causing a chunk of the glass to chip off. 

A chip in the driver’s line of vision may distort the view, posing a safety hazard while driving. In this case, a windshield replacement is advisable for safety purposes. 

But if the damage occurs out of the driver’s line of vision, a chip is usually repairable using car windshield repair kits. Some people prefer to call the rock chips ‘dings’, while others may actually refer to the simple chips when they mention windshield pits.

Stress Cracks

A stress crack is not the result of an impact by a flying object. Instead, it results from stress on the windshield, due to a sudden change of temperature, or a heavy load on top of the windshield. A stress crack is common in areas with extreme outdoor temperatures. 

Frequent use of the defroster on an iced up windshield may eventually result in stress cracks. The same is true with turning on the air conditioning to the maximum in an extremely hot vehicle after the windshield has been exposed to direct sunlight for hours.

Depending on the extent of damage, stress cracks may be repairable. But if the extent is extensive, a total windshield replacement is the safer option.

Edge Cracks

An edge crack is something car owners would shun to see. While these cracks may be small, it is a sure sign of the impending costly windshield replacement. 

Edge cracks happen near the edges of the vehicle’s windshield. Some may appear small due to low impact. But, regular use of the car will soon affect the edge cracks, causing it to spread further until replacement becomes inevitable for safety concerns. 

Unfortunately, cracks at the edges of the windshield are not repairable. So, it is best to consult a glass expert for professional advice.

Floater Cracks

In contrast to edge cracks, floater cracks appear in the middle of the windshield. They are at least two inches away from the edges. 

Just like edge cracks, floater cracks sometimes may appear small at the onset. But, these small cracks will soon become big if not repaired instantly. 

Floater cracks, as small as 6 inches and below, are repairable using a windshield crack repair kit. But larger floater cracks may require a total replacement of the windshield.

5 Major Benefits of Using a Windshield Repair Kit

Using a Windshield Repair Kit

Sometimes we have no other option but to consult a professional, but that’s not always the case. Here are a few reasons why doing it yourself is the better option.

Effective Repair on Broken Glasses

For chips and minor cracks, windshield glass repair kits effectively eliminate the blemishes caused due to flying rocks. The key for a windshield crack repair kit to work lies on special components, such as resin or silicone, that effectively fill the gaps and seal the cracks.

When sufficiently cured, these resins and silicone will toughen the chip with shear strength, almost at par with the glass. By carefully following each windshield repair kit’s strict procedures, you will achieve the best result and effectively restore your windshield’s pristine condition.

Easy to Use

Another compelling reason to use a windshield repair kit is, they are easy to use. Any car owner can perform the application process even without any prior experience. Thus, there is no need to hire technicians, which could add to the repair costs. 

The process is easy, and you can complete the task in a couple of minutes. Most kits come with an illustrated manual or a video demo demonstrating the step-by-step process on how to repair cracked/chipped windshield. The guide will ensure the correct implementation of each step, which is crucial to achieving the best result.

They Offer a Less Costly Option

An average windshield replacement can cost about $300 to $500. But it could be more for high-quality and durable laminated windshields. It can be quite expensive to replace the entire windshield for a minor scratch. Fortunately, the repair kits provide an effective solution to minor damages and scratches, at a cheaper cost for less than a hundred bucks. 

Prevents Cracks from Spreading

A small chip can transform into a big crack under constant stress and pressure of every day driving. Water that seeps through the hairline cracks during heavy rain could further worsen the damage and weaken the glass. By fixing the chip using a windshield repair kit, you do not only prevent the spread, but you also prevent a potential expensive windshield replacement.

Flexible Options

Windshield repair kits are available in major stores, like Walmart and even online on Amazon. These kits are available in multiple brands. Each brand has its own unique solution to windshield damage. Some kits have more complex steps, while others are simple and straightforward. Thus, offering flexibility of choice for the solution to the issue.

While the availability of multiple options provides flexibility, these choices could be taxing while shopping for the best product that suits your needs. For this reason, here are the top picks for the best windshield repair kits in the marketplace today. After extensive study, tryouts, and going through multiple reviews, I have come up with a list of the best brands of repair kits for windshields.
