      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.

                  • 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.
