Most Helpful Customer Reviews
This stuff isn't a miracle and I wouldn't use it to "weld" my engine block. But I think it's just about the best epoxy ever. It's been my go-to epoxy for years - for when I need a really strong bond. It's inexpensive and it's given "added longevity" to many household/garage items that I own. I try to make it a point of always keeping some of this stuff around.
It's five stars for sure, but a couple of things to be aware of:
1) this is not "super glue" and it doesn't bond in 30 seconds. It works best when you can stabilize the item and let it rest overnight (even better, for 24 hours). It's worth the wait.
2) It's ugly. When you mix the stuff together and then let it dry, it comes out a rather unattractive dark putty-gray. But you're not buying this stuff to be stylish.... FWIW, if you do need it to look good, you can paint this stuff. I've used Testor's model paint with a small paint brush and it works really...
JB Weld, I have used for years. These tubes are huge. I undertook several projects using large quantities of glue and the stuff just keeps on coming out of the tube. I think this stuff would almost glue a broken heart.
This is the epoxy to use when you have an overnight available to wait for your job to be done. Stays sticky for at least an hour, plenty of time for larger or more intricate repairs. Good heat resistance to 500 Farenheit, but it starts to break down around this temp, and slightly hotter the epoxy releases very toxic fumes as it breaks down.
