I don't know if that will screw up the expansion/contraction of the rest of the cooker and cause more cracks elsewhere, though.
The drilling the hole at the end of the crack to stop propagation is a really good, really old trick. Do you want to drill all the way through to stop the crack and then fill and touch up the paint on the outside at this point? Hope someone else has tried it on something like your cooker and can give you some first hand advice...
Thanks for the suggestion, but I don't think fiberglass reinforcement will help at higher temperatures (great for lower temps). Above 500F, the JB-weld will still break down from the heat and turn into powder despite the fiberglass support.
