Best Windshield Repair Kit? Let’s Find Out!

I hired a professional windshield repair technician and tested 7 Kits: Rain-X, Permatex, JB-Weld, ClearShield, Athlon Tools, Unioon, Antswish.  Windshield crack repair kits compared resin quality (strength and scratch resistance), ability to push resin into damaged windshield and overall repair quality. I hired a professional repair technician to make a repair and to then provide analysis of each of the windshield repairs made using each brand.

I bought all of the repair products and supplies used to test the products to ensure an unbiased review. So, thank you for supporting the channel.

I like the inclusion of a professional in the field, seeing how he does it and his opinion of the DYI kits.

Featuring a professional, when it's rather hard to grade products was a very smart move.

I used to work at Safelite as a repair tech from 2005 to 2008 in California. Our kit was very similar to the clearshield and the professional's kit (big suction cup with one end acting as a cantilever to apply pressure to the nozzle). We did all our work under a UV shield bubble to get the best results but the process was pretty much identical. I'm very impressed with the results of some of these kits. I miss that job, it was such a great gig that let me drive all day and go to interesting places while meeting all kinds of awesome people.

This is by far the number one consumer product ranking source that I have found. Been watching for a long time and you never cease to amaze me with the quality and objectivity of your reviews. Thank you so much!

[AdmiralDG]

I know I am not alone in the fact that my tool box and my barn have many things in stock due solely to your videos. I am thankful beyond words for the money and effort you have saved myself and all like me.

I got a chip a half inch from the edge of my windshield and it spread out to a 6" crack extending from the chip towards the center. I brought the car to Safelite and all they did was rub on the crack extending it another 2" and then tell me it can't be repaired and I need a new windshield for $600. I drove home, ordered the Rain-X kit on Amazon, and sealed the chip and the crack. Because the chip was next to the edge of the windsheld I used my fingers to hold the other half of the suction cups down for ten minutes while the epoxy did its thing.

It's been over six months and the crack hasn't spread any further. It's visible when the light shines on it a certain way but overall I'm very pleased at saving $585 on the repair.

I used that $300 kit as a teenager when I was repairing windshields and I got to the point where 1) the biggest chips were my favorite to repair and 2) I could make them completely disappear. Also the best film for curing was the plastic from a cigarette pack!

This man has single handedly made me aware of and purchase so many things I wasn't aware I needed!!

[cassandrawelch]

I had to stop in the middle of this to say THANK YOU FOR GETTING TO THE POINT I love that I didn’t listen to 5 min of rambling and “don’t forget to subscribe” crap that everyone says! I subscribed based off this alone. Thank you for not needing to hear yourself talk and for being SO EFFICIENT with time, explanation and providing great reviews. Wow thank you!

I have used the Permatex kit, and it has held up great over the last few years going from high temps, and a few trips into the snow too. The big thing is making sure the area around the "sealing sticky ring" is 100% clean, or the resin WILL force out when you do the "pressurize" step. Otherwise, for tiny chips, it is not a bad kit.

[Timothy-NH]

Huge thank you to Josh to come out and being on camera with out, along with sharing his expertise.

[Todd]

So many times this channel has put out a video that is EXACTLY what I need with PERFECT timing. I just did the estimate for Safelite and it is 159.99 for just 1 chip.
So once again, PF is saving the day.
I appreciate this channel as much as I enjoy it.
❤

I have used the permatex 6 to 8 times with good results. They never cracked, left a wiper streak or discolored. Some spiders were on the large size and were repaired, though none disappeared completely. You're one of the fastest talking Farmers I've come across. Keep up the great work!

[crashline]

Shout out to Josh the volunteer. Nice of him to put himself and his work out there for us all. Thumbs up.

I've been doing windshield repair/replacements for about 10 years now. The first repair kit I bought, and still use to this day, is Glass Mechanix. Pricey kits, but I achieve very nice repairs with it. One thing i'm glad you showed is adding a bit of heat (flame or blow dryer) to the inside of the windshield on the last pressure cycle. You can literally watch the resin flow into the legs of the cracks when doing so. It's very satisfying to watch that happen.

With the Glass Mechanix kit (and with other professional high end kits) you only need to do vacuum and pressure cycles for a couple minutes. Very quick and efficient.

Simply amazing quality work here. Straight to the point, well thought out testing procedures and objectivity. A lot of reviewers and testers should watch and learn from you. Top tier!

[brianmcginley]

The methodologies used for almost all Project Farm tests are by far and away the most detailed and thorough that I have seen. I'd trust these tests more than just about any others I watch on youtube. Also I appreciate the obvious strong efforts to keep the video edit as short as possible.

[pablojones]

I have used the Rain-X kit, and was very happy with the results. Although the repairs are slightly visible if you get them in the right light, they have lasted well, and don't seem to have deteriorated in the 2 years since I did them. 😊

[marcdecockbuning]

Yeah, the opinion and closeup work from Josh increases the already high value of this video review enormously. You can only try and fix the windshield once and you want to get it right. Astonishing work Todd, thanks for that!

Hearing you took extra time to practice usage makes me very happy. I feel like that has been one of the longest running complaints in the comments & I hope you will do so for products you are unfamiliar with in the future. While there are plenty of objective metrics to rate products by, a subjective opinion by someone with experience can be just as valuable & I think some of that can be gained by taking time to familiarize yourself with the tools. These videos are already a fantastic resource for anyone looking to buy a tool & I appreciate your dedication to the channel!
