WEST SYSTEM G/flex Epoxy (2- 4oz): Kayak Outfitting Hardware: desertcart.com: Industrial & Scientific

Review: 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 !
Review: 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.

## Features

- G/flex 650 is a toughened, versatile, liquid epoxy for permanent waterproof bonding of fiberglass, ceramics, metals, plastics, damp and difficult-to-bond woods.
- G/flex adheres tenaciously to difficult- to-glue hardwoods, both tropical and domestic varieties. This is important since many of the exotic and tropical species now being used to replace traditional woods present bonding challenges.
- G/flex has the ability to glue damp woods. It can be used on wet surfaces, even underwater when applied with specific techniques.
- Country of origin: United States

## Questions & Answers

**Q: What is the shelf life of this epoxy?**
A: Detailed information can be discovered by contacting West Systems technical staff at 866-937-8797 or via e:mail at tech-support@westsystem.com

**Q: How much does this 8 oz cover?  Approximately howmany rivets would this cover?**
A: This is a highly subjective question with a lot of variables. If used somewhat conservatively it will easil cover 100 + Rivets.

**Q: Is it somewhat rubbery or pretty firm after it cures?  Could anyone please describe it?**
A: it is not rubbery, it hardens to a very firm coat; how hard is dependent on your mix. it is flexible and holds together; however, less hardener the more flex with coverage. i have used it to gack bows, and it works well.

**Q: is this an 8 oz bottle of the resin and an 8 oz bottle of the hardener?**
A: It's 4 + 4 mate. 8 oz in total

### ⭐⭐⭐⭐⭐ Repaired my leaky fountain when nothing else could
*by C***A on November 7, 2025*

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.
