Product Details

TotalBoat FlexEpox is a tough, 2-part flexible epoxy adhesive used to create permanent structural bonds that dynamically absorb stresses from contraction, expansion, shock, & vibration, and bend without breaking. Use on fiberglass, metal, plastic, and wood—even hard-to-glue, oily domestic and tropical hardwoods. Great for repairing aluminum boats, too.

Simple 1:1 mix ratio, 75-minute working time, & fast cure time make it easy to use and ideal for quick repairs. Also for creating small laminated parts subject to a lot of flexing.

FlexEpox works in a wide temperature range, from 40 to 125°F, and can be applied to damp surfaces. It can even cure underwater. Pair with TotalBoat fillers to suit your application.

Available in an 8 oz. kit and a 32 oz. kit.

Info & Guides
Compare to two-part West System G/Flex 650. TotalBoat FlexEpox maintains its form and properties better at higher temperatures, and is a better value. It also has higher flex tolerances and lasts longer than flexible, one-part urethane adhesives and sealants.

Runnier than expected
By Lucas from Maine

Verified Purchase

Used this product to adhere spray rails on a 30 repco, the epoxy is a lot funnier than I expected, but it did cure well. If using in surfaces where this product can drip or run I suggest using a healthy amount of cabosil to thicken

Bottom Line Yes, I would recommend to a friend

I would buy it again, but it was really thick to work with.
By Joe W from Atglen, PA

Verified Purchase

I called to see if you recommended anything to thin it with. You told me there was nothing I could use to thin it. I wasn't real sloppy to use and It cleaned up well with gasoline. Also, it did well in cool weather. I'll bet it hardens up very quickly in hot weather, however.

Bottom Line Yes, I would recommend to a friend

To be used to repair a polyurethane race car seat insert
By Jerry from PA

I need something flexible and strong to fix flaws/damage in a custom molded expanding polyurethane foam seat insert for an open wheel race car. I bought this product to experiment on some test pieces of molded foam, and it works very well. Adhesion to the foam exceeds the foam's strength, flexibility and toughness is outstanding, and it can be applied to coarse weave fabric to bridge gaps and reinforce thin areas. It's a little too viscous for some applications, but manageable. The only other drawback is that gaffer or duct tape will not adhere well to the cured product (a racing seat insert is normally covered with gaffer tape as a final covering). This can be solved however, by applying the gaffer tape to a thin layer of the epoxy while still wet, which gives good adhesion once cured. Hopefully, this product will be back in stock by the time we have cooler weather (for longer working time), when I plan to do the actual repairs.

Bottom Line Yes, I would recommend to a friend
