sniperdodo,
If it were me (and it very well may be before the season is over), I would give the JB Weld you mentioned a try. Worst case, you try it and it doesn't work. Then you can go to plan b.
If you don't have sap where you are yet, doctor up your pan w/ the JB weld and boil water for a few hours. At least then you'll know if it works before you are into the season.
Note that I don't think it will hold up on the bottom of the pan though (if it's only rated to 300 deg).
Just a thought.
