Permatex 09103 Automotive Windshield Repair Kit For Chipped And Cracked Windshields. Permanent Air-Tight Repairs, With Repair Syringe & Plunger, 9-piece Kit

Used this on a small windshield chip and it worked much better than expected. The instructions were easy to follow and the crack became a lot less noticeable after the repair. Great way to prevent small chips from spreading and save money on windshield replacement.

As other reviews have mentioned, the instructions are a little complicated, but I’m very pleased with the results. While the kit didn’t completely erase my window ding, it’s now tiny and totally manageable. If you look at the videos associated with reviews, there is someone that did a step-by-step. I use that in conjunction with the written instructions and didn’t have any issues with completing the steps. It takes about an hour, mostly waiting/curing time.

I bought this Permatex windshield repair kit to handle a tiny crack on my car's front glass. it was pretty easy to use, and the syringe helped make a tight, long-lasting seal. felt good to fix it myself instead of going to the shop. a few things could be better, like clearer instructions. but overall, it worksd well and saved me some money. perfect for quick fixes when you're on the go 🚗. Glad I have this in the glove box for emergencies!

Almost works well.., Windshield bullseye rock chips are filled but still slightly visible. The vacuum and pressure Q ring seal bursed and shot a into my eye. I had to flush it for 15 minutes. Destroyed my eye and tear ducts and nasal cavity! Can be super dangerous! Be careful!

I was was on the interstate, driving my relatively new car to a car show a few hours away, and THWAP! -- a piece of gravel or something hit my windshield. The damage looked HUGE from the driver's seat, but when I stopped and examined it, it was not as large as a US dime and, in rock-chips-windshield parlance, looks like it was a "bullseye" type crack. I immediately texted my car-exterior guy, asking if he knew of someone who repairs such things and he -- after sympathizing with what happened -- replied in the negative, so I was on my own. I was going through my usual mental gymnastics: if I have the windshield replaced, there's a small deductible, but what if they mess it up and it leaks? Or they don't replace the lane-keeping camera properly? Or, or, or? Sigh. I something-searched for repairing cracked windshields and was reminded of repair kits. Long ago, I'd used one on another vehicle and even had some kid outside the grocery store fix a chip a couple years ago, but neither of those experiences were particularly stellar, so I didn't have a great deal of confidence with the repair-kit route. On the other hand, I figured the worst that happened was I tried a kit, the outcome was horrible, and then I'd have the windshield replaced and deal with whatever came of that. So I ordered this Permatex kit (it was significantly cheaper than a competing kit and that was a big factor in my deciding to go with this one) and watched a video or two from actual people (as opposed to the manufacturer) who threw in a couple of wisdom nuggets that I made a mental note of. The kit arrived with typical Amazon expediency and, finding some time in my schedule, moved my usually-parked-outside car into the garage to begin the repair. (I think that's important because the resin cures by exposure to UV in sunlight, so I didn't want it to start to cure until it was supposed to start to cure.) One of the first steps is to use the provided pushpin to clean out any loose glass or other debris from the surface of the chip. I did that and it dawned on me that loosening up said debris around with the end of a pushpin is fine, but I probably wanted to get that stuff out of there, not just move it around, so I grabbed a cordless vacuum cleaner and used it to (hopefully) remove all of the loose fragments. I figured that would give the resin the best chance at filling in the break in the glass, vs. its having to work around any remaining loose debris. While the instruction sheet is jam-packed with information and I wish that it was a little more checklistable/readable, the rest of the repair process was relatively straightforward. I followed the steps as best I could (my spouse was washing our dog in the middle, so I left to help her during the wait-at-least-20-minutes parts of the repair) and it was going pretty well. I heeded the suggestion to place a paper towel below the chip to catch any resin drips and -- being a careful guy -- was doubting the need for such a thing. However, when I was removing the pedestal from the window, it popped off, and drops of resin shot in unexpected directions. Some of it landed on the wiper blade (which I wiped off) and I didn't see any on the paint, but if it is, hopefully, it will come off. All of which is to say, you may want to proceed very gently when you are removing the pedestal and adhesive circle because there's a bunch of resin in there. Maybe cover the whole deal with a paper towel (in addition to a paper towel below) to catch any resin drops that fly away. Anyway, I think I dodged a bullet there, but we shall see. I cleaned up the excess resin, applied the drop of resin and clear square to the repair, moved the car into the driveway, and -- since it was partly sunny (not fully sunny) -- set a timer for an hour. Due to the plastic and surrounding resin, it was hard to tell what the end result was going to look like, but even at that point, it was looking WAY better than it did before I started. Either way, I figured that it was going to be what it was going to be, so nothing to be done if it was less than great. After the waiting time elapsed, I went out to gently peel off the plastic square and scrape off the excess resin and it looked amazing! The damage evolved from a clearly visible chip through the glass to a small, slightly rough dot (about the size of this letter "O" right here on my display). There was resin goop in the vicinity, so I grabbed some denatured alcohol and a paper towel and cleaned it all up as best I could, trying to keep away from the aforementioned dot, figuring it should continue to cure without my getting it wet with alcohol. While it would be great if that little dot was not there, I'm really pleased with the repair. My exterior-car guy suggested some sort of film over the windshield to lessen the likelihood of these, but I may save that for when I get an actual new windshield and when I get my next chip (which I imagine will come eventually), I'll be trying this kit again. One potential downside (not for me in this case, fortunately) is that one of the first items in the instructions is that this kit is "for bullseye chips only". Looking back, I see where the product page does mention that, but if I'd had a different kind of chip, I might have missed that detail. And when I was searching earlier to see what kind of chip I had, the only images I was finding looked like they came from a 1950s coloring book, so I wasn't really even certain that I had a bullseye chip. Fortunately, I did -- or at least whatever I did have worked with this kit. Phew! While I hope that you never get a chip in your windshield, if you do and it is a bullseye, I hope this kit works for you as well as it worked for me!

I bought this for our gym’s old staff car because the windshield chip kept getting worse from all the early-morning temperature swings. The kit is simple. I parked in the sun, cleaned the glass, stuck the little adapter on, then used the syringe to pull the air out and push the resin in. Took maybe 20 minutes between sets of checking emails. The crack line is still faint if you hunt for it, but it stopped spreading and the surface feels smooth. I’m glad my coaches can drive members home from late classes without worrying about that chip turning into a huge crack. For the price it beats calling a mobile glass guy out to tge parking lot.

Product ultimately worked but when we removed the device taped to the window there was a ton of liquid product in the tube that spilled out, luckily only on the window. I watched the videos and never saw that happen but I did use most of the tube. The product did not cure completely until plastic strip was put on it and car moved into the sun. Did not changed chip appearance that much IMO but when you run you finger across it feels like glass with no chip. Took two stars due to uncured product spilling and some missing tips to removal in instructions. Tip I saw online that needed to be in the instructions was to remove excess filler from inside out leaving the filler over chip to the end then place razor perpendicular to window and scrap side to side. This prevents you digging out filler while flattening the filler over the chip. Technique worked perfectly and you will see why when you pull the plastic square off after sun exposure. Edges of filler come up a little too showing how easy it is to pull out of chip if you’re not careful.

Update: (01/27/2026) The fix is enduring the second winter, which is a rough season currently. The vehicle is a lease, so we are hoping the fix can hold up until this winter is over. *Crossing fingers* Checked recently and no change on the fix since treatment was done. Will update with new photo once cold weather has passed. Thank you Permatex. Original Comment: Bought this kit for hubby to fix a small crack on windshield that is about half inch wide (including the dot and extended lines, just think the planet Saturn). He took his time watching the instruction video a couple time, read and reread the instruction sheet, and prepared all items with rehearsal on all steps before starting. Extra items he had were medical gauze to tape below the adhesive pedestal to avoid resin dripping, well cleaning and microfiber towels and alcohol spray. He also brought the plastic razor saying it's safer than metal one. He said the most important part is actually take things slowly and reread before performing the next step. Also, making sure the pedestal has good seal is very important given how the syringe is introducing pressure into it. For the 10min and 20min pressure wait time, he actually gave 15/30. He picked a sunny day and left the car out for 30min also. The whole process was not messy and resin could easily rubbed off afterward he said. Here are two photo he took after and stated if you shine the light just right, the line and dot are still visible, but otherwise it's very difficult to spot post-treatment. The most important part now is to make sure the fix survives the upcoming winter. Will update this review once winter is done and rating may change based on the result. Here are the summary on Pros and Cons... Pro: -Easy to understand/follow instructions -Task doesn't take very long, but suggested not rushing through it -Definitely much less noticeable after fix applied -Inexpensive DIY kit Con: -Does not magically make damage area vanished as some would claim -Durability remains a concern post-treatment (pending adjustment after winter season) Thank you for reading my honest feedback

高速走行時に飛び石でフロントガラス中央に小傷ができました。近所にリペアショップが見当たらなかったのと、小さめの傷だったのでDIY製品で対処しようと思いました。 同じような商品がいくつか用意されていたので非常に迷いましたが、最終的にレビューを参考に購入を決めました。 日本語の説明書がないことはわかっていましたが、「傷を密閉して減圧し、樹脂を傷の奥まで浸透させる→樹脂を日光にあてて硬化させる→余分な樹脂を付属のカミソリで整えて完成」という流れが写真とともになんとなくわかります。 あとは、減圧し続ける時間や、硬化させる時間をきちんと守ればたいてい成功するのではないかと思います。 付属している注射器や、ガラスに貼り付ける器具や両面テープ、UV硬化樹脂、カミソリといった同梱品がどれも高品質で、つくりがしっかりしているところに関心しました。 気温は10度程度で真冬の日差しでしたが、樹脂はしっかり硬化し、傷もほぼわからなくなりました。 目的が達成できて非常に満足しています。作業時間は、減圧、硬化の待ち時間をすべて入れて５０分くらいでした。 樹脂の耐久性については分かりませんので、その後の様子については何か変化があればレビューしたいと思います。

This is easy to use. Repair was simple following the instructions and where the pit was is now almost invisible from the outside and completely invisible from the inside.

Ótimo, funcionou perfeitamente.

It did a good job for windshield repair. Although it could never remove the big chip completely as magic, it perfectly filled all small cracks which should stop them from spreading further. I would definitely recommend this product.

A windscreen "repair" kit that works. It can't save every time, but worth it for hits that haven't really radiated yet. Makes the bullseye etc a lot less distracting, and we've had repairs that helped hold a screen together for years. Better than the time and money on new.
