The cure for leaking seams and rivets, or adhering patches on boats and canoes, is the G/flex 650-K Aluminum Boat Repair Kit. It also works on fiberglass, wood, plastics and metals.
  • The 650-K kit contains 4 oz. each of viscous liquid G/flex 650 resin and hardener. Mixing ratio is 1:1. It also includes two reusable mixing sticks/applicators, two 12-cc syringes, four grams adhesive filler (colloidal silica), four mixing cups, one pair disposable gloves, four alcohol cleaning pads and complete handling and repair instructions.
  • Mixed G/flex 650 is of a heavy "syrup" consistency. It will run off a vertical surface. The adhesive filler that comes with the kit can be used to thicken it to your desired consistency. Complete mixing instructions are included.
  • 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.
  • G/flex works very well to bond hypalon to hypalon or wood.
  • In addition to its superior bonding to many different materials and its ability to bond dissimilar materials, 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.
