J-B marine weld

Smearedpaint—October 19, 2025✓ Verified purchase

Great product! Used to seal a couple holes in a large trough. Worked perfectly and has lasted 2 months without leakage containing the water! Have used this for multiple things over the years. And it's always worked easily. The combined tube extractor puts out exactly the right amount to mix eliminating worries of getting the proper 50/50 mix for it to cure properly. Highly recommend for cracks, and holes. Read more

★★★★☆

Good product, bur small containers

Craig A. Adams—November 25, 2025✓ Verified purchase

This product sets up well, but not as hard as other epoxies from this company. The packages do not contain a lot of product, but are suitable for smaller repairs, and the adhesion is good. I would recommend it with the caveats above. Read more

Great design

Liz Mitchell—December 8, 2025✓ Verified purchase

This mixed very easily and came with a cap so none is wasted and you can use the amount you need. I filled in holes in a baptistry with this and it's holding up great so far. Read more

Starts to cure in minutes

CW—November 10, 2025✓ Verified purchase

FYI...I think the packaging says "ready to sand in one hour" and they're not kidding. I set up my project, mixed the content inside the two syringes together, and started applying the epoxy working from one end of a crack to the other end. It started hardening on me before I could cover the entire crack. So if you need a little more time, I would buy the stuff that cures in 2 hours. Read more
