            Comments about WEST System G/flex Thickened Epoxy Adhesive Resin & Hardener Kit:

            I was able to quickly and easily repair a slow leak from a crack and a small hole in the bottom of a plastic kayak using G/flex.

            To begin the fix, I cleaned up the areas and mixed the G/flex to a 1:1 ratio. I then used a handheld blow torch to heat up the plastic a bit, just to the point that it looked malleable but not burnt. This was to promote adhesion of the epoxy to the oily plastic surface. I applied the G/flex liberally to fit it in all the spaces, and scraped up the excess. The fixes seem to have taken nicely, and I'll be taking the kayak back out on the water as soon as possible.

            • Laminating Oak Frames

            Comments about WEST System G/flex Thickened Epoxy Adhesive Resin & Hardener Kit:

            I'm always weary of using epoxy as the mixing and curing procedures seem easy to screw up. Pleasantly surprised with the end product as I was unsure of myself throughout the application. Used it to laminate some white oak veneer, replacing original steamed oak frames. I wanted it to have a little flex as to avoid creating a hard spot in the boat as the laminated frames are surrounding by original flexible white oak steamed ribs.

            I let you know if It all falls apart!

              Very easy to use and formed a strong bond after drying. Can't comment on how durable it is as I just applied it two weeks ago but so far it's great.

                    I used a kit and a half of this stuff to fix the six large and 24 small cracks in my Mad River Explorer as well as add two three layer skid plates. Following the guide in JD's "How To's" it came out great. I had one crack in particular that ran down below the water line that made me nervous. My brother and I took the canoe duck hunting last fall and when we got high-centered on a submerged log in some flooded timber one of us had to get out to get the canoe off the log. All 280 pounds of me was in the back, as well as my gear. When my brother started jumping up to push down on the front end better I thought "If it's gonna go, it's gonna go now!" The log was not far from the under waterline crack, but everything held beautifully! No leaks, and the hull still looks great. 1 free canoe + G-Flex + sweat = A GREAT DEAL.It would have cost me around $1800 to buy this canoe new!Thanks JD and Thank You G-Flex!

                      G-Flex is amazing...I am a serious whitewater kayaker, I managed to break a BIG crack in the bottom of one of my boats, and it wasn't just a simple crack, it made a semi circular flap so this needed strength, not just to be filled in. This boat is made of unweldable cross link Poly ( a jackson kayak), so I had essentially written it off. I gave the G Flex a try, followed all the instructions ( grind out the crack like your welding it, abrade all surfaces, flame treat it, etc) and added a piece of glass cloth to the layup to reinforce it. This has held through some heavy duty rock bashing and small drops ( no big waterfalls , but still, a couple of feet onto rocks..) on three river trips so far and it's still going strong. One hint..don't skip the flame treatment, I experimented and it does NOT adhere without it, make sure you flame treat the whole area your applying it to.
