JB Weld might work but I would use CS3204 instead. It has been used successfully on diesel fuel tanks for years.

with Larry. Here's as updated TB with the specs:

If you google "polysulfide tank sealant" you get links like this...

Buy Flamemaster CS3204A1/4 Gray Integral Fuel Tank Sealant - 6 oz. Kit at


Integral Fuel Tank & Fuselage Sealants

Note the difference in working/curing time and the relatively short shelf life. Order it when you need it and mix it when you plan to use it.
