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 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.

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

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.

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'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.

I looked all over for something that works. Saw another review that seemed promising. Just like the other reviewer the trailer manufacturer did not add a support for the clean out which caused it to vibrate and eventually cracked the black water tank. Took some time prepping by cleaning the inside of the tank, let dry by using a leaf blower in the toilet and let dry for a week. Then I scuffed the tank with 100grit and cleaned with running alcohol. Oh I also heated with a hand held torch to get better adhesion. Once all that was done I added a thin layer to the crack trying to force some inside. Next day i applied. Supper easy to mix. Added fiberglass mesh tape to provide even stronger support. Prep is the key.....and fix the problem that caused it in the first place.

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.
