Top 8 Best Windshield Repair Kits

You’re on the way home from work, minding your own business, when *bang* that service truck you’ve been following for the last 10 miles flicks up a rock which impacts yer car’s windshield. Great; just great (let’s see if I can get the TNG clip timing right this time).

But all is not lost (except for that chip of the windshield that just flew out into the weeds; that’s gone for good). There are plenty of repair kits available to those who can’t or simply don’t want to bring their ride to a quick-fix shop. As with all of these things, we recommend you read all the instructions (yes, that’ll be a new experience for some of you) and take your time.

There is a point to be made that some shops and insurance companies will take care of this issue at no charge to the customer, “paying” the deductible in a byzantine blizzard of paperwork that sees no money out of your pocket. However, not everyone is #blessed with such coverage – they might be running a beater that’s in The Crusher’s nursery, and fixing this chip is the ticket to keeping it out of those cold steel jaws (and Johnny Law off your back) for a couple more months.

1. Editor’s Pick: Rain-X 600001 Windshield Repair Kit

It’s tough to start a list like this with anything other than a very affordable kit from a well-known maker of glass products. Said to repair all types of laminated windshields by minimizing the appearance of chips, this product has been reviewed by over 16,000 people which is a very large sample size.

Not everyone was happy, borne out by the 18 percent of customers who gave this item a one- or two-star rating. Still, an examination of negative reviews seems to point to either unrealistic expectations or user error. In fact, the seller explicitly states that the crack vanishes when examined at a 45-degree angle and that poor resin is achieved when it is applied too quickly. This will apparently leave air pockets, a source of consternation for some complainants.


  • Affordable, includes the tools you need


  • Specific set of instructions to follow

Bottom Line

  • Don't color outside the lines in this instance

2. Permatex Windshield Repair Kit

Most of those who carped about the Rain-X kit recommended this stuff instead. Priced ever so slightly higher than the Rain-X kit listed above, Permatex is also a well-known brand that's been around this space for ages.

According to the bumf, this stuff makes a permanent air-tight repair of bullseye-style windshield damage measuring up to 1 1/4" on the round. It's a complete kit that provides everything needed for the repair including easy-to-follow instructions with photographs. Perhaps it's the latter that makes the kit easier to use for some folks.


  • Resin cures by natural sunlight


  • Potential for long shipping times

Bottom Line

  • Popular single-use kit

3. 3M Windshield Repair Kit

Here is another basic kit from a big manufacturer that uses glass resin to seal small bull’s eyes and chips to prevent spreading. Unlike most others on this list, this glass repair formula from the same company that brings us Post-It notes requires no special tools, mixing, or heat.

Perhaps it's this one-size-fits-most approach that hands the product a 3.6-out-of-5.0 star rating; though that's only a couple of decimal places lower than the Rain-X offering atop this list. As always, RTFM before diving into these types of repairs.


  • Includes all you need, oddly long return window


  • Not the best star rating

Bottom Line

  • Yet another option that's similar to the rest

4. Meidong Windshield Repair Kit

The company name of this product will go unmentioned in this overview, lest the repetition of its last four letters triggers some sort of NSFW filter for all you slackers who are reading this on a company laptop or through your work's internet. Perhaps it simply refers to the unit of currency in Vietnam.

Its seller says this is a new generation design with stronger construction and thicker rubber feet on the plastic tool to better secure the device to windshield glass. The auger can be "more easily placed" to help the resin evenly spread over the glass.


  • Results in 20 minutes


  • Lost-in-translation ad copy

Bottom Line

  • Don't say the company name aloud in the office

5. Blue-Star DIY Windshield Repair Kit - 2 Pack

Blue Star is a brand of beer in the land from which I hail but, apparently, it's also the name of a DIY windshield repair kit that costs roughly ten bucks. The company's copy editor must be an exuberant individual since the ad is full of exclamation points. Full of them! Really!

The kit doesn't come with a tripod style repair tool, instead relying on single-use round cups and an injector that looks for all the world like something one would find in a medicine cabinet. Some customers complained about its design but, for the most part, folks were happy enough given the price of it.


  • Very affordable, made in America


  • Some carping about syringe design

Bottom Line

  • Is "better than I thought" a compliment?

6. Clearshield Professional Bridge for Auto Glass

To be clear, this is just one part of the entire arsenal of tools one will need to fix their windshield. However, we're including it as an example of the amount of money professional shops have sunk into their tools and why those facilities don't use the el-cheapo kits listed here.

The bridge itself is well over $100, with various o-rings and end seals costing extra. This doesn't account for the resin or other consumables used in the repair, not to mention the technician's time. Suddenly, a $50 deductible seems rather reasonable for those of us with full glass coverage.


  • Pro tools for the pro is a definite pro


  • Needs many more items to be useful

Bottom Line

  • Helps explain why this repair can be costly

7. AODA Car Windshield Repair Kit

Even though this product's name is ever so close to that of the actor who portrayed Hawkeye Pierce in M*A*S*H but there's no word if it can be found anywhere at Unit 4077. The kit contains 2 bottles of repair resin, good for a couple of jobs or as a cover if you screw up the first one.

The seller smartly notes that buyers must "read our instruction carefully before your repairing job." This is prescient since the majority of unhappy customers for some of the other kits on our list simply didn't RTFM and got mad when things went south.


  • Good price for two bottle of resin


  • Worrying language barrier in the ad copy

Bottom Line

  • Read the instructions!

8. Filba Car Windshield Repair Kit

Names given to off-brand products can sometimes be unintentionally hilarious (witness Meidong, above) but Filba simply sounds like some sort of health food cracker, the type people named Carmyn eat before getting on their bike and riding to the yoga studio.

As for the windshield repair kit at hand, it appears to be more of the same. Roughly 15 bucks in price, includes everything you need to carry out the repair and is the recipient of a decidedly lukewarm star rating. It seems that – as mentioned up top – taking one’s time and reading the instructions go a long way to success.


  • All-in-one kit, apparently good for 12-inch damage


  • Middling reviews (like most products here)

Bottom Line

  • Not a cracker!

Best Windshield Repair Kits: Pane in the Glass

Do windshield repair kits really work?

Yes, they do. If you invested in a branded repair kit and followed the process correctly, you will notice the significant difference after fixing the chip.

What's the best way to fix a chip in your windshield?

The entire fixing process can be divided into three parts, namely:

The Check

To start with, the first thing that you must do is check if the chip is repairable.

If a chip has a hole (space) to inject the glass resin, it is repairable. You can check this by either rubbing your fingernail over the affected area or using the push pin that is shipped along with most repair kits (if you have already purchased one).

In addition, you must also check if the chip has an air gap. For this, you may need to look closely or use a magnifying glass if the damage is small in size. Another test that you can do is through a 25-cent coin. If the coin can cover the chip, it is repairable.

The Preparation

You must first park your car under a shade, maybe inside your garage or beneath a tree. Next, ensure that the windshield is sufficiently warm. If you live in a cold place, you may want to park the vehicle indoors or turn on its heating system to serve the purpose.

Now, place some opaque board on the other side of the windshield, right behind the affected area, so the chip is visible.

The Repair

Once you have successfully crossed the above two milestones, you can follow the step-by-step repair process given below:

· Use a sharp, pointed object to remove the unnecessary glass particles from the chip

· Use the alcohol wipe (mostly shipped along with the kit) to clean the affected area

· Place the adhesive disc on the windshield in a way that the chip stays within the hole

· Place the pedestal over the adhesive disc

· Use the masking tape to cover the surrounding areas of the disc and pedestal to avoid the glass resin to spread on the windshield

· Pour the resin from the tube into the hole of the pedestal. Make sure that the pedestal is filled with the fluid

· Place the syringe over the hole of the pedestal with its plunger pushed inside

· Hold the syringe tight and pull the plunger upward and put the lock on when it reaches the upper mark

· Wait while the syringe sucks up all the air from the chip, and you no longer see any bubbles in the windshield

· Optionally, gently knock the windshield to produce vibration for the air bubbles so they can get into the syringe’s vacuum

· Once all the bubbles are gone, remove the syringe from the pedestal for a second or two and then place it back in

· Push the plunger of the syringe inwards this time to force the resin into the chip

· Lock the plunger to the syringe again when it reaches the lower mark, and leave it there for 20 to 30 minutes to ensure that the resin is fully settled

· If you still see some gaps in the chip from behind the windshield, you should push the plunger in a bit more, and gently knock the surrounding areas. This will force the resin in and spread it evenly to fill the empty areas

· Once everything is done, leave the setup alone for another 20 to 30 minutes

· When the said time is over, remove the syringe, and then remove the adhesive disc. You may need to use a blade or some other sharp-edged object (sometimes shipped along with the kit) to get rid of the disc

· To remove the marks, put a drop of resin on the chip, place the flexible strip over the affected area, and use a flat object to push the remaining air outward

· Leave everything as it is for another 60 minutes or so

· After the given time, place your finger over the chip on the windshield, and use a blade or something similar to detach the strip as much as you possibly can

· Finally, remove your finger, twist the strip a bit, and pull it off

· To remove the resin leftovers and give the windshield a finishing touch, you can rub the blade perpendicularly over the affected area until the entire surface looks even and seamless throughout

Do windshield repair kits work on long cracks?

As mentioned earlier, if you can cover a chip with a 25-cent coin, it can be repaired. If the effect is slightly bigger than that, you may need more than one repair kit and the fixing process could be a bit tedious. However, if the crack is 8-inch or more in size or the chip is present near any of the edges of the windshield, to ensure your safety, you should go for the entire glass replacement altogether.

Can I use J-B Weld on my windshield?

Because J-B Weld also makes windshield repair kits, yes, you can use it to fix the chip on your car. The repair process is explained on J-B Weld’s official website. For your convenience, the link to the page is given below:

    Hey Vivek, you might want to add Crack Eraser's DIY windshield repair kit from to your list if you ever get to update this post. Best kit I've ever used. Used it on three of my cars now, and if you do it like they tell you to, the chip won't even be noticeable. All you have to do is follow the instructions. Saved me a few trips to the glass repair center!

So, if you're not fortunate enough to have coverage or simply prefer taking matters into your own hands, this windshield crack repair kit can be your ticket to keeping your beloved car intact and out of trouble.

  • Redapple2 I d just buy one already sorted. Too many high level skills (wiring, paint, body panel fitment et. al.) that i dont have. And I dont fancy working 100 s of hours for $3 /hour.
  • 28-Cars-Later I'm actually surprised at this and not sure what to make of it. In recent memory Senator Biden has completely ignored an ecological disaster in Ohio, and then ignored a tragic fire in Hawaii until his handlers were goaded in sending him and his visit turned into it's own disaster, but we skipped nap time for this sh!t show? Seriously? We really are through the looking glass now, "votes" no longer matter (Hillary almost won being the worst presidential candidate since 1984 before he claimed the crown) and outside of Corvette nostalgia Joe doesn't care let alone know what day it happens to be. Could they really be afraid of Trump, who AFAIK has planned no appearance or run his mouth on this issue? Just doesn't make sense, granted this is Clown World so maybe its my fault for trying to find sense in a senseless act.
  • Tassos If you only changed your series to the CORRECT "Possibly Collectible, NOT Daily Driver, NOT Used car of the day", it would sound much more accurate AND TRUTHFUL.Now who would collect THIS heap of trash for whatever misguided reason, nostalgia for a much worse automotive era or whatever, is another question.
  • ToolGuy Price dropped $500 overnight. (Wait 10 more days and you might get it for free?)
  • Slavuta Must be all planned. Increase price of cars, urbanize, 15 minutes cities. Be poor, eat bugs
