ANY TIME YOU DON'T WANT AN ACTUAL WELD OR A 'SUPER GLUE', BUT PLAN YOUR APPLICATION
This 'adhesive' product is better than ANY super glue I have ever used before, and I have been disappointed in all of them that I have tried. It's unbelievable in how strong it is. It's clear and black epoxies options are holding this computer together right this moment. Just be sure you have the follow-up stuff ready to use in time before 'SET' so you don't waste your seconds & precious minutes before that 'SET' time. So preliminary preparation is extremely important......but, after that, it's what you would definitely call 'permanent' when the application CUREs. It truly is what a welder would definitely call an alternative to a weld, without the torch & steel rods . The original actually has steel fragments mixed in it. I needed something absolutely non-conductive so I used the epoxy on the computer. Really works.

Best auto body adhesive available in small quantity at small cost.
This is the greatest automotive adhesive I have ever used. In the process of restoring a 50,s antique car. While I do weld some sheetmetal is is either too pitted or to expansive and easily warped. I pretreat rust and grind and clean surrounding area’s. The included mixing tip os great for large area’s and speeds up the placement and anchoring of my patch. Dries in 15 minutes and ready for body work or finishing. Bonds like crazy.

Only thing that worked
I had bought three different types of glue because the rubber bumper guard broke on my brand new Buick Encore. This was the ONLY product that WORKED. This stuff is amazing. I didn't do a very good job closing it however. My only suggestion would be take more time and care when you're closing the container. I feel like I could have gotten many more uses out of it had I.

Car pumper repair made easy
Very easy to use. The two barrels will mix their contents as the gel moves toward the tip. I used it to fix a couple of cracks on my front car bumper. Hardens well and files down easily too. Unfortunately the nozzle can’t be reused once the mixture hardens. It would be nice if they gave an extra nozzle.

Great for sagging bumper
The bumper of my car was detached due to some broker plastic latches. JB weld worked amazing to glue everything back in place. Looks like nothing ever happened. A $8 fix compared to $1500+ quote from my dealer. They are advertising a 15 minutes set time and 39 min cure time. In my case it was still very wet after 2 hours and took 24 hours to cure. Still a great product.

Meh, should have used super glue.
Main complaint is the sort of funnel/spigot attachment really didn’t work well. I ended up just squeezing the stuff on to some cardboard and mixed by hand. The mixing wasn’t difficult though. Second complaint is it wasn’t quite as strong as I was expecting. I was trying to reattach some broken pieces of my bumper. In hindsight super glue probably would have been fine, or better even. I ended up having to just leave the broken bits off and resort to zip ties.
