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

        Many of us who make custom knives use this almost exclusively. Bonding many dissimilar materials can be problematic, but I bond carbon fiber to wood to steel to brass to bone to vulcanized fiber to leather to plastic in any order with consistent success. My only con is high shipping on 2 four oz. bottles!!!!

            Polyethelene Live well tank in a used boat was cracked. Needed to make it solid. G/Flex did
            the trick. Followed the suggested "prep" tips
            and the tank is watertight.

            I had a cracked Polyethelene live well tank.
            This was the only epoxy I could find that was
            suitable for this type of plastic. I really had
            no other options. I worked awesome and the tank
            is watertight!!

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

              Used it on a old Mohawk brand canoe with some severe cracks in the bottom. Applied it along with 2 layers of fiberglass cloth. Took the canoe on an 8 mile trip with some class 3 and 4 rapids. Landed on a rock with the repaired area taking the impact and weight of 2 people and our gear. The R 84 the canoe is constructed of is designed to flex and the fear was the patched area would crack. It didn't crack, there was enough flex in it to give with the surrounding material. The canoe goes back on the water next season.
              Bottom line, it works.

                I used G-Flex 655 on my fuel tank in my boat. I let it set too long and the fitting that the motor draws the fuel thru was so corroded I had to cut it out of the tank.Using a fixture to close the bottom of the hole with a rod in the middle for a thru hole.Once the G-Flex set I removed the rod and let it cure.Because the fixture in the tank was a hex there is no way the repair will pull out of the tank. I drilled and tapped a threaded hole for the fitting.I could not have asked for better results. Cary

                        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.
