G/FLEX EPOXY QT KIT

This is the strongest adhesive I've found for most substrates (the exception being low surface energy plastics). With good surface preparation, I've had excellent results on aluminum, steel, stainless steel, carbon fiber, fiberglass, wood, and many plastics. I did some tests against 3M DP420, the gold standard of toughened epoxies, and this had better shear strength (despite being much less expensive). I've tried acrylic, urethane, and CA adhesives; none matched the strength and toughness of this. This is NOT a quick-dry epoxy. It doesn't even start to harden for a few hours. I always let it dry overnight before using what I've glued with it. It seems to reach almost full strength about as fast as 30-minute epoxies, but it has a much longer working time. Ideally, plan a day ahead. It's a little harder to use than dual-syringe epoxies, of course. If measuring volume is too difficult (say you only need a small amount), you can always weigh the components. The resin is much heavier (about 1.2X), so be sure to account for that. For example, tare your scale, add 2g of hardener, and then add 2.4g of resin.

This product is amazing. It is much more flexible, then traditional epoxy does require a bit more effort to sand but. Gives a great nice finish and sticks to anything. Would definitely buy again

It's the easiest two part high tensile epoxy I've used. Mixes to a honey-like texture and flow. Gives you a solid 35 minute work time, probably longer in cooler climates. I used it to install two 40" (4" x 2") kevlar felt canoe skid plates. Used about 100 grams (50 gr of each) per skid. Lots more product still in the bottles. Wets the fabric thoroughly, smoothes out nicely. Cured in 60 minutes in the local 108 degree heat. Sands easily. Do yourself a favor.

G/flex is amazing stuff, I've had a lot of experience, and sometimes I purchase wholesale from one of the factories in Australia. Just noticed the current price is a little cheaper, anyways compared to their advertised pricing at West system website there are some deals on amazon for sure, especially with the free shipping. I reached out a long time ago to the factories producing for West Marine, and they specifically recommended me the g/flex for oily wood and steel. It also bonds wood together great as well, it is stronger than the bonds of the grains of the wood, and when hit with a hammer, the wood will always break before the g/flex bond. Also you have a great working time, it becomes a little thick around 20 minutes, but I work in a climate always over 85 degrees, sometimes 100 degrees, so other people may have more time. It is sandable in 24 hours (or overnight in my experience), but west marine recommends a full 48 hours for full strength. I have had some skin allergies when working with this, but may be from the wood dust as well, the hot weather certainly doesn't help. It's best to work outdoors, and not to get your nose to close to this stuff, and also wear gloves because it is nearly impossible to get off your hands even before curing. After curing is easier, but then the skin dermatitis will kick in. I use this for bonding steel and wood, and it cures a semi-flexible yellow. It's best to wipe down both the wood and steel with 70% alcohol and let air dry before using. It sands easily enough, but it does tend to clog up sanding belts. This doesn't turn brittle like Devcon 2 Ton. So much stuff to say, but hope this information helps. If anybody has found a good way to wash this off skin while it's still 'hot' let me know. Also last time, the excess epoxy leftover from jobs can be used to coat all types of outdoor handles like shovel handles, pickaxes, hoes, etc. just wipe flat with some waxed paper over the handle. If you have a little bit left over each time, in a few months all your tools will be semi fiberglassed!

Had 4 cracks at the bottom of my boat’s holding tank. Engine would have needed to be pulled to replace the tank. Tried couple other epoxy’s with no luck. This stuff really works. Torched the area and couple coats over the crack. Year later still going strong

Used this flexible epoxy to repair two royalex canoes. Covered gashes going down to the core and then made skid plates using the epoxy alone without any felt or Kevlar strips. Good working time- about 45 minutes at 72 degrees Fahrenheit and 30 minutes at 85 degrees. The epoxy has held up to some rock bashing on the river since. Like all epoxies, it can be difficult to work as it gets more viscous at the end of the working period. I would recommend it for skid plates and repairs on any vinyl or royalex boat.

Fantastic product. If you need to cover a vertical surface, this is for you. Nice and thick.

Worked great to repair royalex canoe
