DEVCON?
#2
Generally the devcon they are talking about is a thicker consistency, almost a putty. So you can press it in to areas and mold it a little before it hardens. JB Weld is more of a liquid and more difficult to handle, but they do have a putty version. Make sure whatever you end up using it has a high enough temp rating for your application.

All the Devcon I've used mixes up thinner than JB Weld or maybe about the same consistency. Certainly not putty like. It gets poured into whatever you're going to fill and you'll need to "dam" any open areas to keep it from running out. Not sure what the actual physical properties are of JB Weld but McMaster-Carr has a pretty good description of what Devcon will and won't do. I've used the steel and aluminum Devcon to fill ports and housings for PP apps and, knock on wood, haven't had any problems with it.

We use "a" grade of Devcon in engine blocks, and it is kind of the consistency of gritty cement when you pour it.
And yes, it runs *everywhere*, unless you're trying to get a nice even fill, in which case it doesn't run everywhere fast enough. That's what air hammers are for!
