I get it at CP. They can probably order it in for you if they don't stock it. JB Weld is definitely the best epoxy I've ever used, it's holding my broken metal body together. the JB Kwik stuff isn't nearly as strong though... it's about as strong as regular epoxy, but dries in four minutes. Like, it's actually solid after four minutes, unlike regular "five minute" epoxy.

I've found a trick which works better than JB weld for larger structural fillet repair. I've found that a big slug of JB is pretty strong under compression, but under tension, I find it to be too brittle and crack prone. It seems that it's stiff, but it propagates cracks.

If you want to make a big gross joint, try wadding steel wool into the area. Heavily saturate the steel wool with good 2hr epoxy (5min is less tough). You can put on gloves and saturate the wool before smooshing it into place. After a couple days cure, you get a slug of steel wool in epoxy matrix which is very strong. I've socked a hunk of the stuff with a mini sledge and only the edges which aren't held in with steel break off.

It's pretty hard to break the major body of goo apart with the steel wool pulling it together. You want the steel wool to be smushed together as tight as you can. More total steel cross section means more steel pulling the epoxy together. All the epoxy does is bond at the outer surfaces and keep the wool from shifting. For even more strength, use stainless steel steel wool. It's available in Can Tire.

i'm repairing my ics lower m4 reciever until i can get a new one. It snapped in half just behind the rear body pin. Amazingly, the upper reciever tabs are completely intact and holding the body together still....

i'm not expecting to be able to mount my sliding stock back on it, but just want to throw the broken part of the reciever back on to protect the innards from the elements.

I get all mine for free from work

I have a few boxes of the stuff at home...

We get it when we buy certain tek connectors for big electrical cables at work. It's used to make the connector explosion proof and on sites where explosion proofing is not specced in the contract, we get tons of the stuff.
