Thickened G/flex® Epoxy Adhesive, 4.5 oz. tubes of resin and hardener, plus instructions and application supplies. Tough bond on many different materials. Waterproof, flexible, permanent.
  • Note: The packaging now refers to this product as Plastic Boat Repair Kit. Please be aware that this is still the same great adhesive that works on a wide range of materials.
  • The 655-K kit contains 4.5 oz. each of thickened G/flex 655 resin and hardener. Mixing ratio is 1:1. It also includes two reusable mixing sticks/applicators, one pair disposable gloves, four alcohol cleaning pads, 10 mixing palettes and complete handling and repair instructions.
  • Mixed G/flex 655 is of a "gel-toothpaste" consistency. It's still very spreadable, but stays put where it is applied.
  • G/flex is a product of West System, a division of Gougeon Brother's, Inc. The Gougeon brothers have been using epoxy resins in boat building and repair for some 50 years.
  • It makes structural bonds that can absorb the stresses of expansion, contraction, shock and vibration.
  • In addition to its superior bonding to many different materials and its ability to bond dissimilar materials, Cured G/flex is much more flexible than other epoxies. This is an excellent property for boat building and repair.
  • Polyethylene (HDPE) is a common kayak and canoe material. Its molecular structure resists gluing by most adhesives. G/flex solves the problem; it bonds well to polyethylene and ABS plastics.
  • At 72 degrees F pot life is 45 minutes. Working time is 75 minutes. It cures to a solid in three hours and cures to its full strength in one to two days. It cures faster in warmer temperatures and slower in colder ones.
  • Clean up is simple. Wipe up spills with absorbent materials. Clean residue before it cures, with alcohol or acetone.
  • G/flex adheres tenaciously to difficult-to-glue hardwoods, both tropical and domestic varieties.
  • It has the ability to glue damp woods. It can be used on wet surfaces, even underwater when applied with specific techniques.
  • G/flex does indeed belong in every boater's repair kit. The more you use it, the more uses you'll find for it - with your boating gear and other sporting and household items. It's easy to mix and use. The instructions that come with the kit are top notch.

How To: Inflatable Repair Adhesives Guide (4:16)

When repairing your Hypalon, PVC or urethane inflatable, or your plastic or composite kayak, it's vital that you choose the right adhesive and solvent for the job. Using the wrong materials will result in a poor repair and wasted effort. In this video, Josh from NRS Repairs shares an inflatable repair adhesives guide to help you understand when to use such glues as Clifton Hypalon, Shore, Stabond, Clifton Urethane, Vynabond and G/flex Epoxy. Solvents for repair prep are important too; you'll also learn when you can use toluene, MEK, acetone and alcohol.

Seems like a pretty good option for repairing a cracked boat IF you have access to the outside AND inside of the crack (ie cracks on the bow are gonna be hard to get to on the inside). The g/flex repair seems a lot more solid than a standard weld, especially when paired with a couple layer of bitchuthane tape. It does seem a bit stiff and brittle, and I'm sure it will crack again at some point...but for now, I'm impressed!

I used this on the bottom of a whitewater kayak that takes alot of abuse. I found that when properly applied, the patch did not come off. It did however crack along the same 5" line that it had repaired.

    I used G/flex to attach an axe head to a plastic handle 2 years ago and have used it a lot without the head working loose. I've used it to repair plastic kayaks and paddles that I didn't think I would ever use again. Its wonderful stuff.

          I first used this two seasons ago to repair an polyethylene plastic canoe that develop a crack directly beneath the seat. That repair has lasted over two seasons. It has gone through several temperature changes and the patch has scraped over innumerable rocks and has held. My buddy used the left over epoxy to seal his foam core kayak paddle. It's working like a charm.

              I applied this to the inside and outside of my Pyranha after melting some plastic from Pyranha onto the crack by heating a putty knife from the back while pressing into the crack. I did follow all the directions about pre-sanding and heat glazing/preparing the surface and it looks like it stuck on there good! The extra product on the cardboard that dried seemed to have some flexibility to it, so I am pretty sure this will hold up fine to river usage and scrapes.

              The stuff is a little on the expensive side, but if it works it will be worth every penny.

                Q:

                What are the shelf lives of the epoxy and hardener when unopened? What conditions are required for storage? Also what is the shelf life after opening and resealing (IE after using a little bit and putting the cap back on) ?

                  A:

                  For all practical purposes, shelf life seems to be indefinite, even after opened and resealed.  I've stored my various incarnations of GFlex for years in an outdoor shed and they have never been affected.

                  Make sure you don't confuse the caps and inadvertantly mix. I've stored in a cool dry place with a snug cap for four years without a problem.

                  No problem on shelf life, Eli. Until mixed the tubes are very stable, just keep the caps on. I've had a set for ~ 4 years, still great.

                  G-Flex is really good stuff and it has a very long shelf life. I bought a package of G-Flex over two years ago and it has been used from the day I got it, the glue will not harden up after you use it. The glue will also go a long way, I use it frequently and still have half the product left. I hope this reply helps.

                  Kay, at 72 degrees F it takes 7-10 hours to get a workable cure, and a full cure can take up to 24 hours. At hotter temps it'll cure faster. It's great stuff but not a quick repair alternative.

                  I used it to bond some aluminum angle to a plastic gunwale that had
                  buckled (I also bolt with machine screws). The canoe has been used
                  once since without any sign of failure. Same for use with fiberglass on
                  the bottom of another plastic canoe. Follow instructions carefully.

                  A:

                  G/flex bonds very well to many materials, including Hypalon and fiberglass. On the G/flex product page there are links to the instruction sheets, in the More Information block. As to it bonding to the gelcoat itself, it may depend on the composition of the gelcoat. Take a look at this online G/flex manual on Fiberglass Boat Repair - http://www.westsystem.com/ss/assets/HowTo-Publications/Fiberglass-Boat-Repair-and-Maintenance.pdf - for additional information.
