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

I picked up the Permatex 09103 Windshield Repair Kit after noticing a small chip on my windshield that I didn’t want spreading into a full crack. I wasn’t expecting professional‑shop results, but honestly, this kit impressed me. The instructions were clear, and the whole process took maybe 20–30 minutes. The resin filled the chip nicely, and once it cured, the spot became way less noticeable — you really have to look for it now. More importantly, it stopped the crack from spreading, which is exactly what I needed. A couple of tips from my experience: make sure you’re working in good lighting so you can see the chip clearly, and give the resin enough time to cure fully. Patience pays off here. Overall, for the price, this kit is absolutely worth it. It won’t make your windshield look brand‑new, but it does a great job at stabilizing chips and improving the appearance. Definitely cheaper than replacing a windshield.

Great kit. I had a nasty stone chip on glass panoramic roof on my Porsche. I saw multiple pros, and they all hesitated to touch it (the complete replacement costs $14K, if the roof cracks). As a last resort, I purchased this kit, thinking that most likely it won't do much. Well, I was wrong. It filled the crack. It was easy to use. Overall, great value for the money. My suggestions: 1/ buy good UV light, and give it sufficient time to cure; 2/ watch some videos to see how to use it, 3/ make sure that resin gets all the way down when you fist pour into pedestal. I had an air bubble and I had to use small straw to drain air before pressurizing. Lastly, take your time, and follow instructions. It is super easy once you know what you are doing.

works decent. i had some minor chips, with one larger chip. used the sticker and syringe on the big chip, then dabbed the resin into the other smaller chips. once dried, used the razor blade to scrape off any extra. it does a good job of filling the chips and making them less obvious and less visible. will probably need to replace the windshield eventually, but this is a good way to hide small chips and make the windshield look decent again.

This repair kit made fixing small cracks at work simple and quick. i really liked how the syringe and plunger helped create a tight, lasting seal. definitely glad i kept it in the car for emergencies. works well, and i didn't need to visit a shop. simple to use even if you're not a pro.

Overall disappointed. Repair improved appearance less than 50% still have a quite visible chip (should have taken before/after pics, but I was too optimistic on this first trial repair). The repair did result in a nice flat fill on top surface (moisture protection) but big internal voids. Some details: 1. I made the mistake of starting the repairs in sunlight, missing the "shaded area" instructions until my third reading DURING the repairs, when I got to final step 10: "Move the vehicle to sunlight". I was too focused on waiting for a cool <75F day with sun (in San Antonio, took till 27Oct). I moved the vehicle to shade between steps 6 and 7, perhaps too late, as the windshield was already warm. So, maybe the poor quality result is all my fault. 2. Cleaning loose glass with push pin created a surprising amount of loose crushed glass. I'm glad I didn't skip on this but it seems a more thorough flush than the teensy alcohol wipe would be appropriate. I felt like I made the chip much more visible by doing the pin chiseling. 3. Removing the pedestal and adhesive disk was very difficult - it had a very good bond (used only the recommended 10 + 20 minute dwells). Doing this removal with the razor blade was not safe, requiring too much force. 4. I was shocked at the flow of liquid resin running down the windshield when I removed the pedestal. I had the rags in place, so no harm done, but I (perhaps erroneously) expected some minimal setting up of the resin during the 30+ minutes after application. There is no setting until sun hits the resin, apparently. 5. Placing the square clear curing strip over the wet resin patch was very slippery and challenging to razor squeegee out bubbles. 6. Moved back to sun, temp had climbed to 78F. After 20 minutes (15 minutes recommended) I peeled off the square curing strip. Resin was cured under the curing strip, but thicker deposits around the edges were still wet and smearable. Instructions do not mention removing excess resin when the strip is applied or how to treat edges of curing strip while wet. 7. With the curing strip removed, you are left with a neat square of raised cured resin, that must be razored off. Otherwise you are left with an obvious square of resin around the repair - the sharp edges at the edge of the curing strip do not disappear naturally. So, the Finishing Tip: "IF the surface of the glass is uneven" is NOT optional. I razored off the entire square area, using the blade to carefully shave directly over the chip repair. Not sure if this is correct or not - directions unclear. Finished surface was more filled and flatter than when I started, but compared to a $50 professional job, this looks like far less than a $5 repair - and I payed more than $5 for this kit. A casual observer would not think that this chip was repaired at all. I will try another brand for my next chip. I should have rated this Two stars, but I figured more would read a one star review - sorry Permatex.

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.

I used Permatex 09103 on a small round crack on my Genesis G90 windshield. I watched YouTube videos on repairing similar cracks and they were exactly like the Permatex instructions. The only thing I did different was to heat the cracked spot with a hair dryer as the glue was slowly filling the crack. It worked great. Bottom line, this product is inexpensive, is easy to use and most importantly it works. Beyond a very small spot where the rock hits it is invisible.

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。

Exactement ce qu.il fallait, utiliser avec succès ,

I purchased this product to fix a very minor chip less than 6mm in size at the top of my windscreen, certainly nothing requiring a new windscreen. Followed the instructions to the letter. The process requires the use of a supplied syringe to create a vaccum and then pressure to push the resin into the chip. Through this process the chip became a crack approximately 8cm in length, requiring me to replace the entire windscreen as it was no longer roadworthy. (See attached photo). The product is absolutely the cause of this crack as the chip had been present for approximately 2 months prior to this and hadn't changed. The moment the adhesive was removed the new crack was visible. I am FURIOUS and this product has cost me hundreds of dollars!! Do NOT use this product unless you accept the risk it could make your issue worse.
