### ⭐⭐⭐⭐⭐ Good Stuff
*by M***Y on January 2, 2026*

Worked perfectly to repair the outer coiled stainless shower hose connection.

### ⭐⭐⭐⭐⭐ J-B marine weld
*by S***T on October 19, 2025*

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.
