West System 655-K Plastic Boat Repair Kit

Very impressed with this kit. Tons of clear instructions. Quality gloves. It even comes with mixing pallets and stir sticks! Like, I've never seen an epoxy kit come with those. I usually have to go find something, like a plastic plate, and some wooden sticks. Soemtimes I dont always have those. This literarily came with everything I needed. Except a mask for fumes, but that'd be a bit much I think, and I had those. It actually worked with HDPE! I've been told "nothing sticks to HDPE" but this stuff bonded flawlessly! I followed the directions, and I think that's very important. I used a torch like it said. Made sure to get it real clean.

If you have a holes or cracks in your kayak this stuff is the best. I've tried a LOT of other epoxies that just weren't flexible enough for hdpe plastics that kayaks are made from that would crack. Quality product that performs exactly like it says it does. I mean, it is a little expensive but you definitely get what you pay for. I had 1 finger sized hole and 4 smaller screw holes and a 2" long crack and it permanently fixed them all and still have 99% of the gflex left.

I had a 5" - 6" crack in the hull of my hurricane trylon kayak. I used this product in conjunction with some patches (recommended by hurricane) which are heated and then applied to form a tight bond to the the shape of the damaged hull area. Unfortunately I was unable to heat the patch warm enough to get a good water tight seal(my bad because all I had was a hairdyer to heat it. I knew after trying to heat it for a little while that it was questionable, but decided to try it anyway).The next day after confirming that it was not a good seal I then had to decide whether to remove the patch and start over or try to seal /fill in the areas which did not bond tight enough to the hull. I chose the latter and ordered the Gflex.It arrived promptly and as soon as I received it I then coated the inside hull of the kayak with GFlex to cover the cracked area and filled the two drill holes I had made (which are necessary at each end of the crack to prevent further cracking). I applied it about two extra inches past the crack and drill holes.. After that, on the outside of the kayak I applied the Gflex around the outer edges of the patch, paying particular attention to the areas where I had been unable to get a tight fit and let it set for 24 hours.Today I spent 4 hours on a river with lots of shoals and rocks so the patch job was tested pretty well and everything remained water tight inside.It is possible that if I had applied the patch correctly the first time with the proper amount of heat that this step/product might not have been necessary. However I do think it reinforced everything.I found the GFlex easy to use and appreciate it coming in a kit form. The little cards and application stick that you use to mix the two epoxys make it very easy to apply. Hope I don't have to use it again, but if I do, I am confident that it will do the job.

This product is really great and easy to use. We bought the kit with the grids because it helps us to measure out the correct amounts to mix. I have used it for quick patches as well as medium size projects. It works well and the repairs have held up in a salt air, humid environment. My ding of a star is the price. It is a quality product but so are many others of its type. this is just in a smaller package that is easier to work with for small projects. It is a bit pricey.

Product worked as described and came with all supplies necessary to apply.

G/Flex 655 Epoxy evidently does exactly what they claim. I have been using it on everything for the past six months. I love the stuff, it stuck to everything I have tried! So I finally decided to give it the "acid test." IPE wood. An oily, super hard Brazilian hardwood that is notoriously difficult to glue. I cut two fresh faces on a pair of 18" lengths of Ipe making a 1.5" x 2" gluing area. Glued them together and let them sit for six days while I went on a short trip. When I finally went out to the garage to stress test the joint I was a bit apprehensive as - using another epoxy- I had several joints fail with another "super" epoxy I tried on Ipe. That other epoxy was supposedly formulated specifically and exclusively for oily hardwoods.......the best of the best it was supposed to be. So I went into the garage, supported the G/Flex-655-glued-up board on two bricks ---- one at either end --- and pushed. It promptly failed. HOWEVER when I examined the broken joint I was delighted to see a nice layer of freshly split-off Ipe covering the entire glue area. No exposed G/Flex at all! Which means that the G/Flex did indeed "adhere tenaciously" to the Ipe ..... just as they say on their website ......... so it was the wood that failed, not the G/Flex. It is expensive but I have glued every project in sight for the past six months and I still have 1/4 of each tube left of the pair of 8oz resin/hardener tubes. I figure unless I have a particularly large project a pair of 8 oz tubes should last me six to twelve months. The 655 is a thicker -- cold honey consistency-- than the 650. So, the assurance that my projects will indeed "stick together" makes it is well worth the expense. I HIGHLY recommend it.

This stuff is fantastic. I had a hole in my kayak and it was an easy fix with this. It's super solid and no more leak in my boat. I've also used it on a couple of other things. One being my motorcycle. The tail piece was broken by the previous owner. I used this kit to put the pieces back together and it's really strong. There was a bit of a gap and I filled the gap with the epoxy. It went right back together like it should.
