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.

Pros/Affordable, includes the tools you need
Cons/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.

Pros/Resin cures by natural sunlight
Cons/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.

Pros/Includes all you need, oddly long return window
Cons/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.

Pros/Results in 20 minutes
Cons/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.

Pros/Very affordable, made in America
Cons/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.

Pros/Pro tools for the pro is a definite pro
Cons/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.

Pros/Good price for two bottle of resin
Cons/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.

Pros/All-in-one kit, apparently good for 12-inch damage
Cons/Middling reviews (like most products here)
Bottom Line/Not a cracker!

Windshield Repair Kit FAQs

I don’t need this!

Maybe you don’t, Mister Moneybags, but the college student or person just scraping by can certainly benefit from one of these kits should the need arise. An ounce of prevention in this instance can keep a chip from turning into a full-blown crack, the kind which can give Johnny Law just the excuse he needs to pull you over.

What’s the difference between all these kits?

Quality of their contents, it would seem. Ones hawked by brand name companies might cost a bit more but it seems – for the most part – there’s a good reason. The result of a job is often dependent on the tools being used, so shoddy plastics and subpar resin aren’t going to help matters halfway through one of these repairs.

Did you really make that Dad Joke in the headline?

The glass one, yes; but credit for the ‘pane’ pun must go to a TTAC commenter who chimed in during prior coverage of this product. See? We read your comments. Sometimes.

Any other advice?

Read the instructions, take your time, and read the instructions. Did we mention you really need to read the instructions? And stop following that service truck too closely!

    Step 1: Stop following other vehicles so closely – even if you don’t get a rock chip, you are constantly getting little micro-scratches on your windshield from road grit kicked up by the vehicle ahead of you.

    Step 2: Practice becoming instantly aware whenever a dump truck enters your general vicinity when driving (worst-case example: a dump truck merges onto the highway ahead of you, while you are surrounded by weak-minded drivers with poor lane discipline and you see big pavement undulations coming up). Keep the vehicle ahead of you in between you and the dump truck (as a blocker) until you have a (completely clear) passing opportunity, then *quickly* pass the dump truck using your right foot on the torque pedal. Do *not* make your pass if you are about to cross a pavement transition (ex. road-to-bridge bump) – this is when things fly off the dump truck. And *never* get caught behind the vehicle cruising alongside the dump truck – because now we’re trapped in the free-fire zone.

    Step 3: When you watch vintage Wheeler Dealers, Edd China tackles a *lot* of projects, but when he needs a windshield replaced, he calls a professional. Do what Edd does.

    Step 4: If you are determined to try a windshield repair kit, remember that a 2-part product (catalyzed reaction) is going to perform significantly better than a 1-part (“no mix”) product. [This goes for paint, adhesives, garage floor coverings, etc. etc.] Also strictly follow the surface prep directions.

      I find I have similar issues with semis in general — they always tend to kick up more stones and larger debris. And in Northwest Ohio, where the only traffic laws followed seem to be the ones related to speed limits, the damned idiots always allowing trucks into the fast lane, where they don’t belong, deserve a special place in he-double-hockey-sticks! The traffic is back up to pre-‘Rona levels, and yesterday morning’s commute, going all of 35mph in a construction zone posted at a variable 55, was the worst, by far, since I’ve been back in the office, all because of the trucks and the rest of the sheep who would likely commit suicide if the sign said “Jump Off This Bridge!”

      I had a total of two repairs and one replacement windshield, all thanks to the trucks, on my last car, and my brother nearly had an entire windshield shatter from a rock hit from a dump truck! I avoid them at all costs!

      As a rule I don’t follow ANY vehicles with open beds or loads. Seems nobody covers or straps down anything these days. I’ve heard the sandblaster effect from various construction vehicles like dump trucks spewing tiny particles of who knows what. So I pass them ASAP.

      I’ve noticed the more sloped or laid back the windshield the more common the damage is. My 350Z collected rock chips like crazy but my C7 is even worse. Contrast this with my 20 year old truck that has 2 to 3 times the highway mileage yet its straight up windshield seems unaffected after all these years.

    Why would I do this? Most insurance companies cover repairs like this with no deductible. Of course, not everyone has full coverage insurance, so no glass coverage. But I would still let a pro do this.

    I will offer one bit of advice – when you get a chip like this, as soon as you can, cut a piece of clear tape (like packaging tape) and place it over the spot. This will keep dirt out of the glass, like if it rains and you have to use the wipers. I did that when I got a small bullseye last November, and got rained on the next day. The guy at the repair shop said that most people don’t think to do that. After the repair, it was basically invisible (you really have to look for it, to see it).

      One of the two repairs on my last car I mentioned was unfortunately right in the direct line of sight, and there was just enough distortion to be a real distraction, especially when driving into the sun!

      Fortunately the next stone hit was hidden in the tint brow which graced 2013 Accords through the first half of the model year, and I didn’t see the actual damage until a crack formed and spread over the course of one day due to temperature extremes, so that first repair went into the recycle bin with the rest of the windshield.

    A double-entendré opportunity missed: the headline could have read “pane in the glass!” 8-D

    Is nobody going to mention the existence of the Star Trek clip in the post?

    1. Did my browser put it there like an ad and I’m the only one who sees it?

    2. Is it related to windshield repairs. (force field maybe?)

    3. Does Matt know that it is tied with M*A*S*H as my all-time favorite TV show ever?

    The secret that the trucking companies dont want you to know…

    Commercial truckers and equipment operators often have stickers on their rigs that state “Not responsible for windshield damage” and “Stay back 500 feet”. The trouble is, they are liable for windshield damage if they are not loaded properly and/or dont have mud flaps or rock guards installed. But you have to prove they caused the damage. This is easy if you are smart enough to have a dashcam (everyone should) or you have a passenger witness.

    Send an email to the trucking company after it happens, attach the video, and give them 5 days to respond. If they dont (or they decline), file a suit in small claims court (less than $1500, no lawyer necessary) and they will settle rather than go to court and lose.

    Passenger cars do not have the same liability unless they are not loaded correctly causing debris to spill out out of the vehicle. This would require a video and a police report.

    A couple of years back, I had a loaner from the Audi dealership – an A5 coupe, as I recall – and took it out for a bit of back-road calisthenics, only to get a big-a** rock in the windshield, courtesy of a dump truck. I have glass coverage on my car, but I never heard back from the dealer and they never filed a claim with my insurance.

    Most strange.

    Personally don’t trust any of them. Doesn’t matter who has done it or how, I’ve still had to have the windshield replaced within a year of receiving a chip noticeable enough to need glass repair.
