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

Easy to use with great results. Watch videos about it first, then proceed. The syringe clip seems flimsy/delicate; I practiced using it a couple of times before beginning the process. Also, as soon as I inserted the resin tube into the pedestal the resin overflowed out almost immediately. There's no way to really tell what amount is in the tube and/or going into the pedestal; it would be handy if the resin tube were clear. No matter, there was plenty left in the tube for the final step. Have several paper towel squares nearby to wipe up spills. I put a full sheet around the wiper blade just below the area I was working on. After locking the plunger in step 6, I lightly tapped around the pedestal to accommodate the release of air bubbles. Finally, my nick/chip was a small bullseye type, less than the size of a dime. This product seems perfect for that type. My windshield was originally damaged while I was traveling on the interstate, at my next fuel stop I put a piece of clear tape over the area (on the outside of the windshield). A glass repair technician suggested I do that years ago when I had another incident like this. I believe it keeps moisture out until it can be repaired.

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.

I am pretty sure it was my fault, but the stopper was not free moving when I got it, so don't be me and check to see if you can move the plunger up and down before you start. Other than that it was a pretty simple operation and the results are great, even after I messed up.

This repair kit from Permatex has been pretty handy for quick fixes at work. I used it to seal a small chip on my truck and it worked well. the syringe and plunger make applying the resin simple. definitely a useful tool to keep in the glove box for emergencies 🚗. glad i have it around now.

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.

This is the closet thing to real magic I have seen in my life. I wish I took a before photo... But... I am very impressed with this product. I had a small rock crack (~0.4inches) and with this product it was completely sealed... Even without the final step (even thou I still did the final step). Will definitely recommend.

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!
