West System 655-8 G/flex Epoxy Adhesive, two 4.5 fl oz., White

I do alot of custom fabrication, mostly on custom cars. This is one of my favorite tools for bonding, sculpting, and finishing. It holds a decent shape before curing, and cures so great - strong - and shapable (is that a word?) I don't write reviews, but G/Flex deserves a bit of my time to give it a big thumbs-up

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.

This is a great epoxy. I use it often.

This stuff works!

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

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.

Used this product to seal a round inspection port into my HDPE fresh water tank. I have been fussing with this for about 5 years trying everything available to keep the port from leaking. Be sure to 'flame' the base tank and don't skimp on the epoxy.

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.
