Fire rated silicone? Good up to 1500*F.

I believe the general consensus I've seen is that JBW works fine in moderation, just not around the fire box. I was going to use it once and searched here and other places heartily, but ended up having a friend weld it. There's another kind rated to a much higher temp designed for automotive applications but the name escapes me. I'll post back if I can find it.....

Edit: CarGo ThermoSteel, rated to 2400 degrees vs JBW good to intermittent 550 degrees.

Cool

Welds cracks and holes in iron and steel
Withstands temperatures to 2400 degree Fahrenheit
Strength increases with heat
Fills cracks and holes and pits
Great for boilers, stoves, BBQ's, furnaces, heaters

Nothing except welding will handle direct fire. In the smoker part though, JB weld should be fine and is good for structural repair as well as sealing. If it's just a sealing issue, then a high temperature silicone sealant (RTV red for example) should be fine.

I had an old brinkman that had a couple of small holes in the firebox, I closed each one of those with a screw, 2 washers, and a nut

Correction to my previous post. Nothing except metal (not just welding) will handle direct fire.

I formed JB Weld High Heat in the seams around one of my side access fire box builds.

Been two years, no cracking or fail.

I was just going to ask the same thing. Now I don't have to. :mrgreen:
