J-B marine weld
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.

Good product, bur small containers
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.

easy to use. saved money.
easy to use. Had 3 chips in my sink and this covered them easily. took about 12 hours to dry hard, but could use sink in 3 hours. now i just have to lightly sand. Was going to get a new bath vanity, and now don't have to!

Highly Recommend this Product.
After trying many other products (and also marble repair services) to fix a seam between two slabs (edge between the top and side panels) on a white Marble bath, this one is the perfect solution. It also lasts despite repeated, regular use and does not turn yellow over time like all the epoxy-based products. Highly recommend!

Starts to cure in minutes
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.
