Best Windshield Repair Kit Reviews & Recommendations 2020

Best Overall

This kit repairs all types of laminated windshields minimizes the appearance of chips and cracks and stops cracks from spreading. It’s good for multiple repairs, and the crack vanishes when examined at a 45-degree angle. The kit works best on round damage one inch in diameter and smaller and cracks no longer than 12 inches. It includes a one-gram bottle of resin repair, a repair device, curing strips, razor blade, and instructions. This kit fills in chips and small cracks nicely and makes them hardly noticeable. It's easy to use, doesn't take much time to complete the repair, and includes enough resin to repair more than one chip. The resin cures only when exposed to UV light (e.g. sunlight), so it is easy to work with and clean up. The kit can inject resin deeply into most cracks, displacing air bubbles and restoring the look of the glass.


One downside is the kit will not work effectively to patch large holes. Also, it doesn't have a pushpin to remove some of the center crushed glass, and the instructions are somewhat technical and may be difficult to decipher. In addition, the product has a strong odor and can adhere to your skin if you don't wear gloves.

Best Value

Available at a friendly price point, the 3M Windshield Repair kit is a popular option for those wanting high-quality at a lower cost. The set comes with everything you need to apply it, going on smoothly and needing no heating. The resin is fairly viscous, with the added thickness contributing to a quick drying speed. When it’s applied immediately after the damage, the 3M set is able to prevent more widespread cracks. As such, it is better to get this kit as a preventative measure instead of as a way to fix damage you already have. It is designed to limit the spread of cracks and therefore isn’t as well-suited towards larger-scale damage. 


For the best results, be sure to use this repair tool right after the damage occurs. Provided it’s used correctly, this valuable kit is a great way to protect the glass on your car. 

Most Versatile

When you are on the lookout for a kit that delivers precision results, the Gliston Windshield Repair Kit is a worthy candidate. It includes multiple parts, each designed to address a step of the repair process. The needle helps you pick away small debris and work on any shape of issue. While some sets only bulls-eye chills, this can be used for cracks up to a foot in size. The suction cups on the four-pronged holder keep the glass pressed together. Once the resin goes onto the surface, it takes mere minutes for it to dry. Finally, the scraper lets you eliminate excess. Taken together, this results in a smooth and attractive result. 


It’s worth a note that, even though this windshield repair set is high-quality, the many steps of the process make it really time consuming. That said, it is well worth the investment since it can fix such large cracks. 

Best for Large Cracks

The YOOHE Windshield Repair Kit is a popular option since it is reputed as leaving very smooth results. It consists of a high-quality resin that incorporates a well-crafted chemical formula that creates a vacuum once placed on glass. The injection tool is fairly easy to control. You can use this in different crack shapes, ranging from webbed to crescents. When the crack is in a linear form, you can use the resin provided it is less than a foot long. For round cracks, the damage needs to be less than an inch across. So long as the resin is applied soon after the crack happens, it is a great way to prevent it from spreading. Meant to dry within ten minutes, this rate is predicated on UV light exposure. If you don’t have access to that tool, sunlight is a good replacement.  


Bear in mind that even though this kit is effective, the drying process is a bit more sensitive. It can require up to half an hour to dry small areas, and it needs more time if you are in a humid environment or the damage is bigger. 

Premium Pick

The Gliston Windshield Repair Kit includes a repair device, bottle of repair resin, a razor blade, five curing strips, and thorough instructions. It works in just 20 to 30 minutes to restore your windshield and prevent the damage from spreading. It works best on cracks that are smaller than 12 inches. The product is simple to use as long as you follow the directions. While not a perfect fix, you hardly notice the crack after you apply the product to your windshield. Another benefit is that the repair holds up over time. The kit also includes enough resin to make several additional repairs in the future.


One problem is if you apply too much force, the product may crack the glass more rather than repair it. Plus, it tends to work more efficiently on round chips. It's also a little difficult to use if you have a tall vehicle, since you have to align the hole inside the tube directly over the crack.

Best Quick-Dry

When the goal is to efficiently address damage and get back on the road, the Raniaco DIY Windshield Repair kit is a suitable option. It comes with a high-grade resin that is easy to apply with the included dropper. The suction and pressure bar are both of good quality, making them effective at helping the resin set. Helping this kit stand out from the rest is the inclusion of the UV light. This type of radiation is necessary to complete the curing process on the resin at a chemical level. It ensures that it not only looks smooth but that it actually works. You can use this kit on any kind of damage, though if it is circular, the diameter must be less than an inch across. Drying in less than half an hour, this kit is great for those focused on saving time. 


Keep in mind that only the resin which is exposed to the ultraviolet rays will dry properly. Be sure to use the included light to get the full benefits of the resin.

Best for Smaller Damages

Bamoer's second-generation windshield repair kit features a thicker rubber foot for added security. It's easier to attach the auger, which allows the resin to spread more evenly across the windshield. The deep penetrating resin minimizes a crack's appearance, and it works in just 20 to 30 minutes on cracks less than 12 inches long. It’s easy to use and apply on your windshield and can completely fill in a dime-sized bullseye in the glass. It's a great value for the money and costs just a fraction of what a repair shop would charge. The instructions are clear, and overall it makes cracks look much less visible.


However, if you receive a deformed suction cup, it won't stay on the glass and the resin will leak. You may also need to apply water to the suction cups so they stick better on the glass. In addition, while it lessens cracks and blemishes, it doesn't completely remove them.

Best Multi-Surface Sealer

This flowable silicone sealant repairs cracks on windshields and glass as well as on sunroofs, RV vents, vinyl, rubber, and steel. It is resistant to extreme temperature fluctuations, vibration, and shock. It dries clear, is waterproof, and seals leaks in hard-to-reach areas. This product works really well on smaller leaks and makes the surface area water-tight. It does a good job of sealing around older windows and windshields that use gaskets. You simply put a small bead around the edges and it seeps into the small openings that are leaking.


However, it can be a challenge to use this product on vertical angles because it has a tendency to drip. Some users also complain that it's not more "flowable" than typical silicone caulk. It may also cause a bubble effect on the repaired area.

Easiest to Apply

If you’re on the hunt for a solution that is easy to apply and works well, the BBear Windshield Repair Resin offers a lot of value. It comes with two containers of resin, each with its own dropper. The glass correction formula goes on smoothly and doesn’t leave behind many bumps or rises. You can use it on cracks of any size, though the smaller the damage, the better it works. The chemicals are safe, non-toxic, and don’t create any foul odors. Once in place, it can actually fortify the window since the resin isn’t sensitive to extreme heat or cold. It takes only a few minutes to dry and doesn’t require any UV light for activation. Convenient and efficient, this resin is popular for its simple and straightforward design. 


It warrants a note that, though the kit is designed to work quickly, you will still need to scrape away any excess resin and wipe down the area. This step also lets you know that the seal is effective. 

Honorable Mention

When your priority is stopping a crack from spreading, the ATG Windshield-Fix Repair Kit is a terrific option. It is designed to address small chips in the glass as well as thinner cracks. The set itself comes with 16 different pieces, each with a different role. The powerful injector and sealing rings contribute to the airtight vacuum. The high-grade resin fills the hole while the adherent parts are there to hold the surrounding glass tightly together. The resin leaves behind a smooth result, preventing distortions in vision when you look through the glass. Coupled with the scraper, you can get smooth and even results from all angles. The shelf-life of the equipment is fairly lengthy, making it a good tool to keep around in case of an emergency. 


Bear in mind that the resin is really powerful, but you only see full effects if it’s cured under UV light. As a result, either repair the glass in direct sunlight or use a UV lamp in order to get the best results.

Types of Windshield Repair Kits

Resin

The best windshield repair kits utilize resin with a high viscosity that makes the substance resistant to flowing and thereby more stable. In order to create a tight bond to the glass, the resin should also prevent shrinkage. Synthetic resins commonly include the ingredients methacrylate and acrylic acid as well as hydrogen, carbon, and oxygen.

Windshield Repair Kit Pricing

  • Less than $10: The majority of windshield repair kits are very affordable. They typically cost less than $10 both online and at retail locations.

Key Features

Shape of Damage

Select a windshield repair kit that works on the exact type of damage on your windshield. For example, most repair kits can correct defects shaped like a star or flower. This means there was a single point of impact, and the damage spread outwards from that point. Other shapes that can be corrected include cracks, chips, and bull's eyes.

Other Considerations

  • Sensitivity to Temperature: In order to cure the resin patch, the best windshield chip repair kit will include instructions on the best temperature range to make the fix. Most kits recommend curing the repair in direct sunlight, while others say the exact opposite. It's essential to follow the product's directions in order for the resin to properly cure.
  • Resin Quality: The best windshield repair resin repairs chips and cracks, but it needs to be a high-quality substance. When looking for the best windshield repair kit, find one that has a denser and thicker material that dries clearly. You want the resin to blend into the windshield without leaving a big blemish. Lower-grade resin kits may dry in a pale yellow shade.
  • Volume: The size of the crack or chip in your windshield will determine how much resin you will require to complete a repair job. Typically, one windshield repair kit should be suitable for a one-time repair on a small crack on a single windshield. If you're repairing more than one windshield, you will need a kit that can be used more than once.

Tips

  • Try to repair a cracked windshield as quickly as possible. The longer the windshield sits, the more likely it is for dirt to get into the crack. Dirt can be hard to remove, and the resin may not properly bond to the glass as a result.
  • Even the best windshield crack repair system will leave a mark on your windshield. Some repair kits produce more clarity than others, but the crack or chip will not be completely invisible. These kits strengthen the windshield but do not completely hide the damage.
  • Look for a kit that has all the accessories required for the job: resin, an injector, curing strips, adhesives, applicators, and a razor blade. Alcohol wipes, pushpins, and a pedestal are also great to have to complete the task.
  • When repairing a crack, make sure it isn't bigger than 1.5 inches in diameter. Also, make sure the star- or flower-shaped crack is smaller than 6 inches in length.
  • Be patient when repairing your windshield. Take your time, thoroughly read the directions, and become familiar with all the tools before you start the project. If you rush, you may make a mistake.
  • Before making a repair, thoroughly clean the windshield with a mild detergent and let it dry. Also, remove any loose particles from the damaged/cracked area before applying the resin.
  • When spreading the resin, determine how much pressure you need to apply (too much can make the crack worse). Use only quality resin, and smooth it out enough so that the windshield wiper blades don't get caught on the substance and loosen the patch.
  • When you finish using the windshield repair kit and the resin solidifies, use a razor blade to scrape excess resin away from the windshield. Then clean the glass with a cloth.

FAQs

Q: Is it better to repair or replace a cracked windshield? 

A: If the crack or chip is smaller than the size of a quarter, a windshield repair kit can do the job just fine. A good-quality DIY kit will prevent a rock chip or crack from expanding but will not remove the damage, and correcting a cracked window is not very costly. However, if the crack, bullseye, or star is directly in front of your line of sight, you may want to replace the windshield. Also, if your vehicle is old, the windshield may not hold up as well under stress and probably should be replaced.

Q: How do I use a windshield repair kit? 

A: Position the applicator over the crack, and insert the extension base over it. Put the resin tube over the extension and tighten it until resin replaces the air inside the applicator. Press the syringe to insert six to 10 drops of resin inside the applicator. Put the provided screw inside the resin chamber, and turn it clockwise until it tightens. The resin will press against the glass. After five to 10 minutes, unscrew and remove the applicator.

Q: How do you keep a windshield crack from spreading? 

A: If you don't use a windshield repair kit, there are other ways to prevent a crack from spreading, but they are temporary solutions. Eventually, you will have to purchase a repair kit or have a professional correct the damage. Short-term solutions include using super glue or clear nail polish. You can also park in the shade or garage to prevent the crack from getting worse.

Q: Can I use a windshield repair kit on other things? 

A: You can use a windshield filler kit on headlights, picture frames, smartphones, and other glass objects that are cracked. It is a useful product to have to repair many types of glass objects.

Final Thoughts

Our pick for the best windshield repair kit is the Rain-X Windshield Repair Kit. The biggest benefit is that it can be used for multiple repairs. It is also easy to use and makes chips and cracks significantly less visible.
