Those look like good probes, Gregg! About the JB-Weld, or high-temp silicone (gasket maker) issue: I use the red Permatex, but I'm not concerned about "food grade" because I'm not sticking the silicone in the meat! I wouldn't use an epoxy, like JB, because you need a bit of flexibility in the wire. I would also be concerned that the thick epoxy putty would not penetrate the probe and make a truly watertight seal, which the silicone will do.
