G/flex is a tough, resilient epoxy engineered for a superior grip to metals, plastics, glass, masonry, fiberglass, and wet and difficult-to bond woods.
It is currently available in two versions: G/flex 650 Epoxy (sold separately, a two-part (resin and hardener) liquid epoxy, and G/flex 655 Thickened Epoxy Adhesive with a thickening agent already added.

I keep this on hand for joining teak,sepale, fiberglass, G Board, etc. It's a 1:1 ration and mixes evenly. It can be colored. It can be used to fill screw hole, smooth rough wood before painting, and laminating.

Impressed with its ease of use, versatility and durability. I used it to repair my aluminum boat with great results and a number of other household projects.

The product works great. But the resin tube on my first order was cracked and oozing a little product out when I opened the package. I contacted Jamestown and they immediately shipped me another package with both resin and hardener. When I opened this new package, neither tube was leaking, but both had indentations like the resin tube in the original shipment - exactly in the same place (see first attached photo). I don't need another replacement, but I am going to have to be careful how I store the tubes for future use. In both shipments, there was no visible damage to the shipping box, so I suspect the damage to the tubes may have happened before the final shipments to me. In any case, I suggest West System should look into this for their future customers. One note: in both shipments, the tops of the tubes were face down in the product box. This puts the tops against each other. If they put one tube in with top up and one with top down, this would give more space between them - maybe put a piece of cardboard or thin foam between them, as it appears the damage is due to one tube pressing against the other. Also, I suggest that Jamestown open up the product box and inspect the tubes before shipping until this packaging problem gets reviewed and revised.

I would probably give 5 stars but I have witnessed performance over time. I really like the thickened product which makes it easy to mix and apply and has a good working time. I repaired scratches dings and gouges in my royalex/vinyl canoe. My putty knife a over spread cleaned up well with acetone.

Purchased the 2 quart kit and used it to attach a polyethylene riser to a fiberglass septic tank. No fasteners were used and the epoxy formed a permanent waterproof bond below grade to prevent the intrusion of rain water. Well worth the expense. Do it right the first time and never look back.

I use the product to fill cracks and voids in natural edge slabs. The wood I use is oily. I have had no issues with bonding at all. I have been using this product for about 10 years now.

I have owned a mad river royalex canoe about 30 years. At one point the gunwales were not released when I lived in Fairbanks AK. Winter hit and it resulted in 23 rather extensive cracks. G/Flex 655 was recommended to repair them and it is working wonderfully. I haven't put it back in the water yet but ots Jan in WI Highly recommend it.
