If you’ve just discovered that your windshield is damaged, thanks to right-to-repair laws, you can buy the best windshield repair kit and fix it yourself. They should be simple to use, provide easy-to-follow instructions, and should come at a reasonable price. But first, you’ll need to consider how extensive the damage is to your windshield. Tiny cracks, chips, or bullseye marks can be quickly repaired so that your windshield maintains its integrity. But if you have severe cracks in the glass, this might be something best left for the professionals.

Next, you’ll want to think about how easily you can use a DIY kit to repair the damage.

Along with considering the extent of the damage and whether you’ll need a single-use or multi-use kit, there are other factors you need to keep in mind, too. Not all products can be used in harsh temperatures, for example. If you live in an extreme climate, you may need to look for repair kits designed to work even in very hot or cold weather.

Beginner’s Guide to Windshield Repair Kits

What is a Windshield Repair Kit?

Windshield chip repair kits are a DIY solution designed to help you easily fix small cosmetic damage to your windshield. In particular, this can include small cracks caused by road debris like rock chips or other falling objects hitting the glass.

Moreover, this road debris can also cause dents in the body, which is why you’ll want to invest in a high-quality dent repair kit. Additionally, if you have a warranty on your vehicle, you may want to learn how does that warranty work, in the event you’re prohibited from using a repair kit.

On the other hand, you can also review Question 1: the Right to Repair Law, which permits you to use a platform where you can run vehicle diagnostics using a mobile app.

Along with correcting the physical appearance, these kits also provide preventative damage control. They help maintain your windshield’s integrity and prevent the damage from spreading. However, more pervasive damage may be too extensive for a DIY kit. In this scenario, it’s best to go to a professional auto body shop to replace the entire windshield with a new one.

Windshield Repair Kits vs Other Glass Tool Kits

A windshield repair kit is a specialized DIY repair solution to help car owners preserve their windshields, minimize the potential for damage, and improve their cosmetic look. But there is a wide range of glass tool kits that you can purchase for your car. Often these are designed to enhance your car’s appearance or improve performance while you’re driving.

For example, plenty of windshield kits are designed to repel water by applying a hydrophobic layer that ultimately improves your windshield wipers’ ability to remove water. This ensures that your vision isn’t compromised if you have to drive in rainy or snowy conditions. These kits often also improve the cosmetic look of your windshield by creating a glossier effect. However, while useful, a water-repellent glass tool kit isn’t designed to correct damage and is not essential for maintaining the integrity of your windshield.

How Does a Windshield Repair Kit Work?

While many brands offer windshield crack repair kits, they all operate similarly. Resin is the most common sealant used to correct minor windshield damage. This durable resin is also highly viscous, ensuring that it properly flows into all cracks and openings and dries clear. It is usually cured using UV light. Typically this type of resin is also shrink-resistant, which prevents cracks or chips from growing.

As you shop for a windshield repair kit, you’ll find that there are two main types — consumer and professional solutions. Consumer options are typically designed with enough excess resin to fix one or two cracks or chips at most. Still, the kits contain everything you need to manage a DIY repair, including the resin, UV-activated curing sheets, razor blades, push pins, and a pedestal or repair bridge to help guide the resin during the repair process.

In contrast, professional kits are often made to manage multiple repairs. These kits include more durable parts such as drills and drill bits, resin, metal bridges, and reusable parts. Between the two, professional kits are understandably more expensive. With a professional kit, it’s possible to pick a version with several bottles of resin that will allow you to make up to 100 repairs. Still, the windshield integrity may be ruined if you have extensive damage. In this scenario, it’s better to go to an auto body shop for a consultation and recommendation for the next steps.

Why You Should Buy a Windshield Repair Kit

Thanks to right-to-repair laws, you’re no longer at the mercy of your dealership or local auto body shop. This can be ideal for people who are confident in their repair skills, want to save money, or don’t have the time or interest to wait for an auto body shop to get around to fixing their car.

Are Windshield Repair Kits Worth Buying?

  • You Have Minor Damage: A small ding or chip on the windshield should still be fixed as quickly as possible to prevent the damage from spreading. But this type of issue is precisely why simple windshield crack repair kits were invented.
  • Your Windshield Gets Damaged After Hours or on the Weekend: Your windshield gets cracked on a Friday night, but your dealership can’t fit you in until a week later. A good DIY windshield repair kit can quickly get you back on the road—and on your timeline.
  • You’re Trying to Save Money: Professional windshield repairs can sometimes cost hundreds of dollars. Assuming that the damage is minor, opting for a DIY repair kit can save you significant money.

Why a Windshield Repair Kit May Not Be for You

  • The Damage is Extensive: DIY windshield repair kits aren’t designed to fix large-scale damage. In this scenario, you’re going to need an auto body shop to manage professional quality repairs. In some cases, replacing the windshield is safer than trying to manage a patch job.
  • You’re Not Comfortable with a DIY Repair: Not everyone feels confident enough to start tinkering with their car. If this is you, that’s okay — go to a professional.
  • You Have Insurance or a Warranty to Cover Repairs: Depending on your insurance policy or dealership coverage, you might not have to come out of pocket for cosmetic repairs like a windshield chip or crack. If that’s the case, you may prefer to have the professionals manage the repair.

How Long Do Windshield Repair Kits Last?

This is going to depend on the kit that you select. We mentioned above that there are two types of repair kits — consumer and professional kits. Consumer windshield repair kits are usually designed to fix one or two minor scratches or chips. They also come with less durable tools and parts, meaning there will be a limited number of total repairs you can complete before replacing the entire kit.

In contrast, professional repair kits can come with enough resin to sometimes cover more than 100 repairs. Additionally, they feature more durable tools, including drills and drill bits. This means that the tools will still be functional long after you’ve exhausted the original resin that’s included. Of course, this depends upon you treating your tools correctly, cleaning them after each use, and storing them somewhere that helps preserve their lifespan.

How to Choose the Best Windshield Repair Kits

While picking a quality windshield repair kit with effective materials is important, other factors also come into play. Considerations such as your comfort level with repairs, the extent of your windshield damage, and even environmental concerns can all influence your final purchasing decision.

Windshield Repair Kits Key Factors to Consider

1. How extensive is the damage?

Always start by assessing your windshield’s damage and how long ago it occurred. A DIY kit can easily manage a small nick or chip here or there with a DIY kit. In contrast, major cracks — especially those across the driver’s side field of vision — might be better treated by a professional.

Also, think about your car’s age. The integrity may be irreparable for significantly older vehicles that still have the original windshield. Again, if you have an older model car, you might be better off going to a professional for an evaluation.

2. Are you comfortable managing a DIY repair?

Right-to-repair laws might allow people to manage repairs independently, but that doesn’t mean everyone wants to do that. Think about your comfort level with working on cars. If you’re not confident enough in your ability to do this repair, don’t risk it. Just go to a professional.

3. Do you want a consumer or a professional repair kit?

You’ll need to consider how often you have windshield damage to answer this question. If you’re a road warrior, the risk of chips and cracks from road debris is higher. And as a result, you might need a professional solution that gives you enough materials to manage multiple repairs. However, if you don’t experience windshield damage that frequently, you might be better off with a cheaper consumer windshield repair kit.

4. Are there environmental restrictions?

Resin windshield repair kits are fairly easy to use. But some resins may not respond well when you try to repair your windshield in extreme hot or cold temperatures. Always read the manufacturer’s guidelines and ensure that the kit you want to purchase is compatible with your region’s climate.

5. How easy is the application process?

Even if you’re an old pro at DIY car repair jobs, that doesn’t mean that you want a repair kit with a complex list of steps. Instead, look for solutions with easy application methods and tools, such as a jig to guide the resin to the damaged site or resin that relies on sunlight to cure.

Keep in mind that ease of use and severity of windshield damage works conversely. More serious cracks typically can’t be fixed with a simple application process and should usually be paired with kits that require more steps.
