G/flex 655 Thickened Epoxy Adhesive

Sticks to anything. Used it to seal the bulkhead on my 16.5’ kayak front bulkhead. It is made of ABS plastic. This epoxy exceeded my expectations, was recommended by the reps at Hurricane kayaks. Easy to work with, dries hard as a rock but flexes with my boat. I use my kayak 50+ times a year. Worth every cent

Great product. I used it to repair a crack in my 10 foot prowler boat. The crack was horizontal about 10” long including an inside and an outside bend. I watched a how to video on utube? Followed the step by step instructions and had the repair patch done in fifteen minutes. Let it dry for 24 hours and put it in the lake. Two of us fished out of it for two days. Worked great. I would highly recommend this product if you’re looking for a permanent patch for a abs plastic boat. This product is meant for underwater use.

I bought then to glue a 3" uniseal to polyethylene, and ended up gluing 2 one side the worst damaged side of the polyethylene glued well and is sitting under pressure underwater now, however the other side which I damaged in the process of taking everything apart to glue the bad side Did not hold completely near the bottom of the seal it separated slightly, although i suspect it had to do with the preparation since it was my first time I probably did not get it 100% right, although It's also underwater and not leaking. To add my neighbor fixes cars and was looking for a new glue to use for repairs he took the piece of card board I mixed the glue on and attempted to crack it only causing him frustration, and eventually just cutting it with my big pick axe lol, he says it wont crack and the look on his face said I don't understand. I would buy this again, I have also used it to repair my Nike sandals which split all way through on the side of both sandals as well as the top strap starting to come loose from the rubber, But it was no problem for this glue. I have size 15 foot, and often end up catching the front of the sandal on stuff bending it in half at times as i step forward with 250lbs behind my step, but no cracking or damage at all since glued i am surprised.

400 miles into a 2500 mile trip I noticed I had a leak in my black water tank and found a crack at the outlet that connects to the drain pipe. I tried other products and methods to repair with no success. I found the Gflex on Amazon and it worked amazing. I first let the tank drain - a slow, smelly drip into a bucket for a few days. Then followed the recommendation to try and get the adhesive into the crack to do an initial seal. I was able to flex the tank enough and used a meat injector to apply to both sides of the crack the best I could. I let that set up and then used Gflex and fiberglass cloth from a bondo repair kit (following the directions that came with the kit) to create multiple layers. The Gflex has the perfect consistency to achieve excellent results. Filled the tank with water - no leak. Drove a couple hundred miles - no leak. Took care of business - no leak. Due to the flexibility of the adhesive, and fixing the original problem that caused the crack (the factory forgot to install the bracket to support the drain pipe), I am sure this is a permanent and way less expensive fix than replacing the tank.

I've been using this to patch small cracks and spider cracks in the transom of my 1970's fiberglass boat. It's easy to mix up and thick enough to apply upside down on the bottom of the boat *without* having to let it set up (semi cure) or mix with fillers like sawdust to make "peanut butter". It's already thick enough (even in a hot Arizona garage) and sticky. I apply it with a plastic mixing stick after opening up the cracks with a dremel. It seems like the perfect toughness after curing. Not too brittle and not too flexible. It should flex with my old "wet noodle" hull and not crack again. It sticks to anything and self levels itself while applying to make a smooth repair. After curing it is so clear it looks like there is nothing in the cracks, which is funny.

I've used epoxy for 45 years. Professionally (construction) and boating and around the house. This is the best all-around epoxy I have ever used.I've kept the tubes in my garage for about five years, using them when ever I need an adhesive. I finally used up the tubes and ordered some more.This epoxy is thicker than most, so it is good for vertical surfaces without running down. However the thickness is not great if you are spreading it very thin like a paint.This epoxy is also very slightly flexible, I've even used it to successfully repair some shoes. The flexibility is probably what keeps it from being as brittle as standard epoxies.Don't forget to order some plastic stirring sticks, it helps greatly with the mixing and application of the adhesive.

There's nothing quite like G-Flex. Waterproof permenent repairs on vertical surfaces with no drips. Glues, bonds and fills gaps on many different materials. I've used it on boats, kayaks, cars, home repair, wood, plastic and fibreglas. First quality.

pricy but plenty of material to work with, I've spent as much money to get 1/2 as much, pretty large tubes. It"s not as thick as I expected. It's will stick on a vertical mend better then most everything else, but mine did sag and so you have to work with it, slow set and plenty of work time and when your working on holding tanks (mine) its usually a contorted position. No leaks on the first road trip so I'm happy but if it doesn't leak in the next 2 years I'd call it permanent and give it 5.5 stars.
