Strong and Reliable Epoxy!
The WEST SYSTEM G/flex Epoxy is excellent! It bonds strongly to a variety of surfaces and has great flexibility, making it perfect for repairs that need a durable hold. Easy to mix, easy to apply, and works exactly as advertised. Highly recommend for anyone needing a reliable epoxy.

Great for snowboard repair
Pretty good stuff at a good price. I used this on my snowboard where parts of it started coming apart so clearly I needed something waterproof. Once I cleaned the surface and mixed the stuff I then applied it however thick or thin I needed it and it stuck to the board fast. It's been a long season and the board is showing wear and tear so I'll again apply this stuff so yeah it works.

It works and it works WELL ( MAKE NO MISTAKES )
This is ((SERIOUS)) EPOXIE it is beyond j.b.weld which is 3900 psi holding strength ! This is rated @ 5000psi ,used it on some large pressurized glass projects it is as strong as the quartz glass . Excellent stuff to keep on hand , drys slightly amber ,not clear !

High quality marine epoxy
Bought this three times, maybe will be a fourth time to repair my ailing wooden sailboat. The working time is excellent and it hardens well in a few hours. I added some coloration to my mixes to make it compatible with the Mahogany wood the boat is made from.

Works on Guitars!
Used it to fix (rebridge) my poor and abused acoustic guitar. I figured if it can hold a boat together and not give in to moisture, it’ll probably work pretty well for my guitar whose bridge (the little piece of wood that holds the strings under the sound hole) keeps lifting and pulling away from the body (needless to say the rest of the guitar). Easy to apply and it cures quickly and very thoroughly. Unsurprisingly this is the ONLY glue that has worked for my guitar so far, and that’s because it’s epoxy and not glue! It’s been a journey and I’m glad it’s finally over and a working solution has been found. For those who are curious or looking to do something similar: I previously tried Titebond trim glue (it’s what I had) which failed spectacularly and pulled off beautifully like fresh melted cheese on a pizza (which was NOT the desired outcome), then I tried Titebond original two times since people claimed it would work fine (it doesn’t, I live in south Texas), and after throwing away my old proprietary bridge and buying a new one and struggling for a few hours I finally used this and it works great! Only took about two teaspoons total (one of the clear and one of the orange). It was easy to spread and the perfect thickness and I haven’t had to worry about my guitar bridge coming off at all since.

Works well, long pot time, waterproof, clear,
Excellent epoxy for niche projects like building custom knives which I engage in frequently. No color, very clear, will take expoxy stain, waterproof, Food safe, a little thinner than I would like. Drying time is fairly long but the tensile strength is really good. My one star deduction is for the price and the containers. This product has gotten very expensive and the containers are really annoying to dispense accurate proportions of the resin and epoxy. A large twin syringe with a push handle would solve the mixing issue. The price increase would be warranted with an improved dispensing system

Repaired my leaky fountain when nothing else could
I had a brand new 40” tall outdoor resin fountain that i forgot to empty the first winter I had it, so it ended up with cracks and leaks along the bottom seams. I tried all kinds of sealants, from pourable to sprayable, to no avail. It’s a tight space that was impossible to reach a hand inside to work. After giving up and trying to shop for a new one and not finding one I liked nearly as much, finally ChatGPT turned me onto this stuff. It’s awesome and worth the expense. This stuff is amazing because once you combine the epoxy and hardener, you do have a full 45 minutes to work with it before it becomes immovable. I was able to tilt the fountain and guide it around the uneven surfaces to make sure it was coating all the edge seams. It pours and penetrates regardless of moisture or debris. Pro-tip: After mixing, warm it in a water bath while stirring until it has the texture of honey. This will make for a faster pour that will seek out tiny fissures.

Resurfaced a Mad River 16’ Royalex Explorer. G/Flex mixed with Cabosil (filler), paste pigment, then applied with plastic squeegee. Worked pretty good, see how it endures over the next couple years

Used this to repair broken keys on a budget piano/synth keyboard. Keys have been cracking at the hinging flex point at the back of the key. Used a regular epoxy but it is too brittle and only lasts about a year. The G/Flex epoxy appears to be much more durable and flexible....although only time will tell.
