Time to give up on the Thermoquad?

I've heard jb weld does not hold up to the junk they sell now. I think that's why the goop I used failed. Worked fine when it was just gas, but now with the alcohol in it, it doesn't hold.

At the same time, I fixed the crack in the front of the bowl with jb weld before I found the other stuff. It seemed fine. But that is really more of a dry area anyway.

I did fix the gas tank in the Dart with it a year or so ago, but I haven't put enough gas in it to know if it is still holding.
