5.0 out of 5 stars apply it correctly, November 9, 2009

and this is great stuff. some pointers
Epoxy glues have a limited shelf life. Buy yours at a small store where the merchandise doesn't move quickly, or keep it 5 years on the shelf and it won't work well. Don't apply it at temperatures below 60 degrees. Spend at least 2 or 3 minutes mixing it. I use a timer to be sure. Surface preparation is the key. It must be completely grease free. I use naptha (lighter fluid) alcohol, and acetone in that order. The surface MUST be rough. I use a file,very rough (#40 or #60) sandpaper or a sharp Exacto blade to make multiple cross hatch cuts- this will even work on most steels. Apply the mix carefully, put the pieces together so they don't move for at least 8 hours.
Do all that and the bond is very strong.

5.0 out of 5 stars Handy Hubbies Love It, February 12, 2009

I gave this to my husband, Timothy, for Christmas (among other things). Yes, call me strange and I'll answer. He thought it was an odd gift, but he thanked me later when inevitable occasions to use it came up! He used it on our aluminum hull boat and on his fishing poles. Recently we had a contractor working at our house. When his air compressor cracked, he asked my hubby if he had any J-B Weld. "Well,yes, I do!" was my husband's answer. J-B Weld saved the day!

5.0 out of 5 stars couldn't live without it, April 8, 2011

I think little elaboration is necessary after seeing other good reviews.
I have used this stuff over 20 years, probably gone through a half dozen of the industrial size packs. Saved many things from the dumpster by fixing them instead. Love the water cleanup and non toxic thing, I usually end up wearing stuff like liquid nails and PL construction adhesive which removes skin, I can be a big happy mess with JB weld and wash it right off me and my tools. In short, no credible home handyman OR professional should be without this around.
Like another user I fixed a radiator with it, a neighbor's nissan 240sx. He rear ended some guy and broke the top, about a 3" long fissure along the base of the fill spout (the plastic part) 2 years later when he moved to ohio and drove it the 1500 miles there it still hadn't leaked a drop.
I remember the packages in the old days used to have these outrageous testimonials like "I fixed the axle of my 10 ton farm tractor" and at first I'm all "get outta here, how is that possible?" but with proper prep,(roughing up to give it something to latch onto) cleaning, thorough and accurate mixture (if you err it's probably better to be light in the hardener not heavy) and good long cure time (I give it twice the max if possible and never play with it while it's drying) I don't think those claims were at all absurd any more.
If you don't have JB weld you aren't fixing things as good as those of us that do. Can I say that?

Fun tip: if JB weld is running away from where you want it to be in warm weather after applying, you can use a strong (like rare earth) magnet to draw it back toward where you like. Or take your magnet and hold it under a piece of aluminum plate and move it around just for giggles. It's steel!
