Rated 2.0 out of 5.0 by DIYEsq Not nearly strong enough for what I needed, but probably OK for tasks that just need regular glue
My wife got a decorative garden metal flagpole stake. No sooner than an hour after she got it, the flimsy flagpole broke off. We're talking about a steel "twig" about a 1/4-inch in diameter that attaches perpendicular to a 5/8-inch diameter steel stake. Mr. Fix-It (i.e., me) was asked to come to the rescue, but I'm more a woodworker than metal expert and have rarely used epoxy-type adhesives.
On a friend's advice, I tried JB Kwik Weld. Mixing it evenly was clumsy. The steel is jet black, the hardener is a beige, and they're supposed to mix to a dark gray color. The steel gushed out of its tube on its own as soon as I took the cap off (like it was alive!), but the hardener came out of its tube slow like a slug even with a good squeeze. So besides the steel being "self-wasting," getting a 1:1 mix ratio was tricky. So was knowing when you've mixed enough; the instruction just say to "mix thoroughly." But I got the dark gray color almost as soon as I first swirled the hardener and steel together. If you mix too much, it will start to "goo up" on you and is tougher to apply. As far as actually applying it, it was tricky doing so without either dripping or smearing it where I didn't want to.
After putting on a pretty good layer, I clamped the "twig" to the stake and assumed my project was over. But when I came back the next day, it had cured "gooey" with a poor bond. The twig sagged as soon as I stood the stake up, and then just fell off after a few seconds. I ground off the goo with my Dremel in order to try again, thinking I just needed to mix it better. This time I also drilled a shallow hole in the stake first so that the "twig" would have extra support besides just the Kwik Weld. Nope - still gooey, still weak, and didn't hold under even light pressure. After grinding off the goo from try #2, I thought maybe 3rd try was the charm. No again. Clearly, Kwik Weld wasn't going to work.
Just to be clear - before each bonding attempt, I pre-cleaned with an industrial-strength Zep degreaser, sanded/filed/gouged the surface area of both workpieces for several minutes, and "mixed thoroughly" as the directions said. Still had poor results.
Also, the bottom of the hardener tube unraveled during my 3 tries (probably from having to over-squeeze to get enough out). Hardener started leaking out and I could "re-seal" the bottom, so I'm sure there's no shelf life left on that tube now. The fact the tubes themselves aren't even sturdy is ironic, and reflects how un-sturdy the bonds they (didn't) form were for me.
As unsatisfied as I was with JB Kwik Weld, I could see it working OK for projects where the workpieces have a larger surface area being bonded together and gravity is not going to be a factor. But IMHO, epoxy-type adhesives are meant to work in precisely those types of situations; otherwise, its just regular glue! That's kinda all JB Kwik-Weld felt like to me - regular old glue, but with a lot more fuss to using it.
One final note - ended up buying Gorilla Epoxy for my project, and it worked great on the first try. That's what I'll be buying from now on.

Sets in 5 minutes. Naa. Opened and tried a new pack from Omalleys Auto Parts, and that is certainly not accurate. Temperature was 90 F. Taped it together and hoped for the best.
I do not like the stuff also because they do not state anything about what it is made of.

Rated 5.0 out of 5.0 by sloan when mixed together it is the best cold weld ever.
I had a cut off 3/4"x 6" water pipe no threads comming from a wall. Pipe could not be threaded. I was told by a old plummer guy who said get a 1"x3/4" cpvc reducer then reduce the 3/4" to 1/2" for water line and get some sand paper. Now he said get some JB Quik and 1 rubber glove. He said clean and sand the pipe the best I can then mix the JB Quik working fast with glove on coat both pipe and reducer with JB Quik then with a turning motion slip reducer on pipe hold in place using gloved hand to smove around edge of reducer. Give it five minutes and you can run cpvc from that point on. Ohhh by the way that was almost 3 years ago.

Rated 5.0 out of 5.0 by UmAsiya This product is awesome!!
I had to repair a door that had gotten kicked open. I kept a piece of the wood that broke off, hoping that one day it could get repaired. One day I decided to venture into my local Home Depot store and I came across this product. I looked into others, but this is the one I decided to try. I figured I have nothing to lose before I spend a lot more money to repair it any further. I followed the instructions and glued the small wood piece back, put some pressure on with my fingers/hand and it worked!! It is super strong! It held itself better than I had ever expected! I tried to pull it off with a lot of pressure and it didn't break off, not even move out of place. I highly recommend this product for wood repairs. Also, I only needed a small amount. But because my kids assisted me in misplacing one of the tubes I need this stuff again. Let's see how it holds off on my new project. I'll follow up with that one later.

So many of us have used the standard 25 minutes J-B Weld that well takes 25 minutes to cure. As many people know, that is a long time to keep something clamped and it usually in my experience takes a few hours to actually cure. The other day I had to make a repair to my car and I went into the big Orange box to pick up some J-B Weld. I came across the 6 MINUTE J-B Weld KwikWeld. I’d never seen it before (might have been out for years, I don’t know). I personally didn’t want to sit and hold a turning lamp in place for several hours so I figured I’d give this stuff a shot.
J-B Weld KwikWeld comes in the two standard tubes. Just like the longer open time formula, this is a 1 to 1 mix. I noticed that the viscosity of the chemicals will change dramatically with temperature changes. In the house it was about 10 degrees F cooler than outside and once the tubes heated up, the chemicals have a slight flow to them before they are mixed.
I cleaned off the surfaces to be glued, mixed up the J-B Weld and applied it, then taped the parts together to hold them in place. Being that I was bored waiting for the curing process to finish I decided to play with the remaining mixed epoxy. Sure enough, at about the 4 minute mark it started to really show signs of setting up. At 5 minutes, the epoxy was very tacky and difficult to move. At a little after 6 minutes, the J-B Weld had setup and wasn't going anywhere.
Later on in the day, I took the car for a drive and the light didn't move at all. The J-B Weld held as expected.
Ok so why four stars? Simply put it’s the tubes. They are a pain to store and keep clean. Also, if you use the cap to pierce the tube, you now have chemicals on the cap which can add to the mess. While J-B does make a dual tube applicator, my box store didn't have them in stock.

Rated 1.0 out of 5.0 by Chan Didn't even keep my car's headlight's mounting brackets secure
So this product definitely is quick to set and that's probably the only good thing about it.
I purchased this based on all the positive reviews I've read and was disappointed. My car's headlight mounts broke off so I decided to use this to mend it. I cleaned the area with alcohol and allowed it to dry. Then I mixed this up in a 50/50 mix and began to apply it. After letting it set for about 10 minutes, I put a tiny bit of stress on it by holding the headlight by the mount. It hasn't broken yet so great news.
The next morning, I went ahead and began installing it back into my car and guess what... Every mount that was repaired with this stuff broke right off!! I'm gonna try the original JB Weld for this application but I'm VERY disappointed in this product. I've heard people using it for their firearms in their reviews which is extremely hard to believe.

We have used JB Kwik Weld for so many applications in asture environments it is impossible to catalog all the uses.
We have fixed outboard motors (saltwater environment), caving ladders, broken machine gun mounts, broken steering linkages and so many other items. Usually, we use it as a temporary fix until we can get back to base to get the right parts to actually replace the broken part, but there are some items that the JB Kwik Weld worked SO well that we simply left well enough alone.
Seems like a MUST for a homeowner, rancher, construction, farmer, military, firefighter, etc. when parts might need to be repaired NOW.
I simply cannot understand the review below that says it was unsatisfactory becuase it did not dry clear. No where on the package does it claim to dry clear.

Worked like a charm for my project. Similar to the first review of locking PVC to Threaded Pipe.
When it says 6 Minutes, they mean it. Be prepared with all of your components before you start. You will not have time to get them together after this product is mixed.
In response to odiesdad... It says "Cure Color Dark Grey" right on the front of the packaging. What is there to be fooled about? Giving the product a low rating because you failed to read the packaging is just silly.
