A chip or a small crack on the windshield can be a frustrating sight to see, but it is something that requires immediate action. Time is critical when it comes to windshield repairs, and it helps if you have a preferred brand especially when the crack or chip obstructs the driver’s line of view. While shopping for windshield repair kits, you’ll come across a plethora of products in the marketplace, and 3M is a brand that stands out from the rest. I hope that my 3M windshield repair kit review will help you assess if the product truly lives up to its marketing promises.
But before we dive into the depths of the review, it helps to know how to shop for cracked glass repair kits so as to do away with selection stress and enjoy your shopping instead. There are a couple of features to look for that can make it easier for you to find the right product. So be sure to check out the quick buying guide when shopping for the solution to your windshield breaks.
Windshield Repair Kit Buying Guide
The windshield is a sensitive part of the car as it is exposed to heavy stress that comes from daily drives. The wind load is deflected and absorbed by the windshield as the vehicle increases speed. It is also subjected to fluctuations of indoor and outdoor temperatures.
So it’s no wonder that a small bullseye break can quickly turn into a big crack as you continue to drive the car with a damaged glass that has not been immediately fixed. Hence, you must fix the windshield crack as it happens, and make use of a windshield repair kit for the job.
Things to look for in a Windshield Repair Kit
The market is overflowing with numerous brands of automotive glass repair kits that can be a little overwhelming for the inundated car owner. But if you know what to look for in a product, shopping for one can be simple and fun. For cracked glass solutions, there are only a few things to keep in mind, and you will have yourself the best product that suits your needs.
Scope of Repair
The first thing you should look for when shopping for windshield repair kits is the repair scope. Not all products are designed to fix any and all types of windshield glass damages. Some kits are specially made for cracks, while others have the necessary tools for star breaks, bullseye cracks, and chips. You could end up buying a cracked glass repair kit like the Versachem flowable silicone when what you actually need is a windshield chip repair kit that contains more tools for fixing chips and bullseye breaks, like the 3M windshield repair kit.
Likewise, you must also assess the type of damage on your windshield in order to find the perfect match of repair kit that will fix your windshield issues. If there are multiple damages on the windshield like cracks, chips, and bullseye, you may need a repair kit designed for multiple uses. While most products are for a single-use only, you can purchase a bundle pack for extra savings.
Damage assessment is a critical part of the repair process. No matter how quick and easy, there are limitations to windshield repair kits. Most products can only fix cracks up to 12 inches in length, and chips or star cracks up to 1 ½ inch in diameter. Damages beyond that would require a total windshield replacement. In any case, the first step is to match the damage with the right kit, and everything should end up well. You can fix or minimize the visibility of the cracks with the right product.
Another important buying factor is the type of material used by the brand for the repair. For windshields and glasses, flowable silicone and liquid resins are the most commonly used materials. There’s a separate article on the pros and cons of liquid resins and silicone for repairing glass breaks and windshield cracks. It would help to know the differences between the two types since each has its own significant advantages for specific damages.
Bullseye breaks and spiderweb cracks usually demand a more complex repair process, and liquid resin repair kits are normally the ideal choice. These kits come with repair tools for pushing the liquid resin into small gaps of the break to create a vacuum seal. The liquid resin also works for cracks and chips. On the other hand, the flowable silicone works well as a windshield and glass sealant, effectively creating a water-tight seal around the damaged area.
The Repair Tool
What really sets a particular brand unique from its competitors is the repair tools that come with the windshield repair kits. Each brand has a distinct applicator tool designed to force the advanced resin formula into the cracks, it is only for you to decide which one would be best for you.
Regardless of the design, a windshield repair tool usually contains a resin chamber for the temporary storage of the liquid resin, a suction cup for better grip of the repair tool during the repair, and head screws for pushing the liquid into the cracks.
Some repair tools are fairly easy to use, while others have more complicated designs. So, if you want a quick fix, go for the kit with a straightforward repair tool design, like the 3M repair kit for windshields.
Curing Time and the Curing Strip
Curing is a critical process since this can greatly affect the quality and durability of the repair. If you fail to observe the proper curing time, you could end up with a faulty repair job. So, it is no surprise if you see review feedbacks of unsatisfied customers saying that the product didn’t work. But on the flip side, there are happy customers who said it worked, and that is probably because they did exactly as instructed.
The quality of the finished product is the result of an accurate implementation, and curing is one of the fundamental steps that should be properly observed. The curing strip is another significant item in the kit that distinguishes one brand from the other. Some kits have no curing strips at all thus, increasing the risk of degrading the quality of work.
A curing strip serves to protect the adhesives or the liquid resin applied on the glass breaks during the curing time. The curing strip protects the repaired area from dust and air, thereby allowing the resin to harden and solidify in an air-tight space to provide the best results. 3M uses a clear plastic film instead of a curing strip for their glass repair kits.
Cost is always a determining factor while shopping, as the availability of resources can either limit or expand your choices. But price shouldn’t be a problem when it comes to windshield repair kits, as it is already the cheaper option to a complete windshield replacement, which can be extremely expensive. But when you are down to a couple of choices among similar products from different brands, the price point will become a significant factor.
In general, most rock chip repair kits are affordable, with a price range of 10 to 20 dollars. However, these products are usually for a single repair. So, if you have multiple cracks on the windshield, you’ll have to buy more kits. However, there is one brand, the American Windshield Repair Systems, which has an American Mini repair kit good for 50 repairs. The price per kit is also substantial. But it is also cost-economical with an average cost of 5 to 6 dollars per repair.
Thus, you must properly balance your choices to get the most value of your investment. You can invest in an expensive yet cost-economical kit if you are facing windshield crack problems too often. But if it is only an isolated case, you are good with a single-use kit for a minimal investment.

Brand credibility is one of the core advantages of 3M, with more than a century of worldwide operations across a broad range of industries that include automotive, energy, electronics, safety, manufacturing, healthcare, and consumer markets, to name some. Today, 3M has a global presence in more than 70 countries, offering 60,000 products for homes, hospitals, schools, business establishments, and commercial and industrial settings.
Its scientific and technical innovations fueled the company’s success over the years, allowing 3M to be a regular in the Fortune 500 list. 3M has become a household name synonymous with quality for its innovative and durable products supported by good customer support. So there is no doubt it can live up to its marketing promises of providing one of the best solutions to cracked windshield issues.
The 3M rock chip repair kit is already a complete set with all tools necessary for the repair. The kit contains a bridge assembly where the suction cups are attached by two Phillips head screws. The bridge assembly also serves as a platform where the resin chamber is mounted.
An injector with an o-ring is also provided inside the kit to assist you in applying the liquid resin into the chamber. When you are done with the repair, you have a clear plastic film with a similar function to that of a curing strip to allow more effective curing of the resin and achieve a durable result. Thus, the kit has everything you need and requires no mixing whatsoever.
When it comes to the procedure, there are only a few easy steps to follow. The kit comes with a detailed instruction manual for an accurate implementation of each step, which is critical to avoid a bad repair. For a quick overview of the procedure, below are a few important steps to follow.
- Clean the area and get rid of any dirt. A stick pin is provided inside the kit for cleaning deep cracks of dirt, tiny debris, and loose pieces of glass.
- Assemble the bridge and place it over the chip or bullseye break.
- Screw the resin chamber into the bridge assembly until the tip touches the surface of the windshield.
- Fill the chamber with the liquid resin using the dropper provided in the kit.
- To apply the liquid resin into the damaged area, screw the injector into the resin chamber.
- Once the crack is filled with resin, remove the bridge assembly and wipe off excess resin on the surface.
- Apply the clear plastic film and cure the repaired area under direct sunlight for about 30 minutes. A longer curing time may be needed on cloudy days with no sunlight. Alternatively, you may cure the area using UV light (not included in the kit).
- Once cured, remove the plastic film and scrape off the excess cured adhesive with a scraping blade provided in the kit.
Looking at the above steps, you can ascertain how easy the steps are, and you can complete a single repair job in an hour or two under direct daylight for curing. But you still need a glass cleaner for a glossy finish and to make the glass look new. But this is optional, what matters most is the chip becomes less visible and should not cause a distraction.
