No - JB Weld is a brand of steel-filled epoxy. Pretty much any steel-filled
epoxy will do the same thing. It is available at most hardware stores in a
variety of forms, from slow set to very quick set. All take about 24 hours
to develop full strength. I haven't used liquid aluminum, but if it is
aluminum-filled epoxy it should be pretty similar.

Then I think it's worth a try. Be sure there is no pressure inside to try to
bubble up through the epoxy - applying it at night when the temperature is
already dropping should do the trick - and be sure there is no trace of oil
on the pipe.
