JB Weld for the win !
First time trying JB Weld. Used to repair a snapped aluminum casting. It worked quite well, followed instructions and part I repaired appears stronger than new.

Easy to use
I used this to fix a kitchen sink faucet handle, the gear stripped and would free spin. The instructions were clear, I used the cardboard Amazon box to mix the 2 parts, applied it to the gear sticking out of the sink, stuck the handle back on it, and left it overnight. By morning the sink handle worked like new! It's been about a week since applying it and its still holding strong. The shaft sticking out of the sink was metal, and the gear inside the handle was plastic and striped smooth. I was worried it wasn't going to bond well but a week later and its still going. Great product IMO.

Strong bond
Very strong bond for iron gate repair. Easy mixing. Seems to be holding up impressively so far. Definitely would recommend for any small metal bonding job.

Não cumpre o que promete
Não colou a bola do meu câmbio e ainda ficou cinza, cara de sujeira.

Like molten metal
This really does set like metal & has excellent adhesion. I’ve often taken claims about “hard as steel” but this stuff is very good. I have repaired garden hose sprayers & load bearing brackets. It’s really effective.
