Liquid G/Flex 650 is a two-part (resin and hardener) mixed at a 1:1 ratio. Choose from 4 different sizes of resin/hardener: 8 oz. kit, 32 oz. kit, 2 gallon kit, 4.75 gallon resin only, and 4.75 gallon hardener only.

I have started building a few one-man boast and decided to try this adhesive. It far and above exceeded my expectation. Very easy to use with fantastic results.

I like the long working time; much longer than everything I've used before yet total cure time is still 24 hrs. .

High quality epoxy

This product is working great so far, used it to fix a snowboard with splitting layers due to edge damage. Followed the directions and clamped the damaged area overnight. I've ridden it about 6 times since the fix and it's still holding, very flexible material.

used product to bond a steel piston to a carbon fiber tube. the piston assembly is for a HW97K spring airgun. We went through this whole rifle for a complete blueprint tune. The bond is holding up now at over 1200 shots and works perfect. I do not think anything else but G/Flex would hold up to this kind of force for thousands of cycles. Best epoxy we have ever used!. I give it 10 stars!!!!!

I make knives and I used it for the handles. I also used it to bond other metal to wood projects. The longer cure time is more than made up with ease of use and quality of bond. Will continue to use it.

I have an inflatable kayak that had three holes. One was on a seam. I used the epoxy glue to put on a patch and on the the seam I just used the glue and no patch. I took the kayak out a couple of days later and had not leaks.

Meade and Jan Gougeon were friends of mine, and excellent boat designers. Their West Systems products are the finest in the world. They worked directly with some of the finest chemist's in the world at Dow Chemical to formulate West Systems Epoxies. We use the West System G/Flex 650 for the structural aspect of our racing r/c boats. The physical properties of this product are far superior to competitor's products... it's all about the modulus of elasticity- it's more stress absorbent. Of note, for small projects such as ours, we mix by weight rather than use the mini pumps to meter the components out.

We have been using G-Flex epoxy to bind the rudder posts to the fiberglass skins when building or rebuilding rudders. It has eliminated the problem of leakage around a metal post to a fiberglass skin. Also, in fast turnaround damage repairs, it ensures bonding between a damp rudder skin and the underlying foam core. This ability has saved many a charter crew from cancelling charters. Superlative product.
