Loctite 1919325 0.85 Oz Metal & Concrete Epoxy

As a long time user of various epoxies from hardware and home improvement stores, this is the best I have found so far. I thought JB Weld was supposed to be the best because it is so common. This is far better than JB Weld and I am going to use it for a lot more than metals. I found out about it from a video comparing epoxies. The other brand that looked as good is "liquid steel". The grey color is same as the package shows, but it is very shiny. I would prefer clear white and black options, but the shiny grey looks really cool a lot better than I could have imagined. It cures really hard, which is really nice for some purposes, but makes it more vulnerable to breaking like glass from the shock of drops on a hard surface. I made a fidgit spinner (4 ball bearing hubs glued together) with it that I can't break by prying the device with my fingers, but it breaks one bearing off if I drop it onto cement.You have to cut the tip off lower than you expect to open it up. The end cap requires you to put it on with the correct left-right orientation so that traces of the hardener do not mix with the resin part, otherwise the cap would be epoxied in-place before the next use. I wish I had found out about a glue this good 40 years ago as a teen.To get best grip, roughen surfaces with sand paper, clean with soap and water, then dry with lens-cleaning cloth and acetone or rubbing alcohol. At a minimum, clean with soap and water to get grease off the surfaces. The biggest problem in sticking that people do not realize is oil from their finger prints.

I had a crack in my van door hinge attachment. After having an expensive new door latch put in I did not want to spend more on welding. This stuff to me is as strong as a metal weld. I sanded once, applied and then redid that again for 2 coats of really strong steel like weld. This version won the test I watched with 7 different brands as well.

Very pleased. Resilient after setting. Color is weird, kind of gray or green. Used around my pool edge where concrete patch failed. This has Benn in place at least two years and I no longer use concrete for patching the concrete surface. I use this as it holds up much better.
