4 years ago I patched a small hole in the bottom of my tank with that roll epoxy you knead into a ball. Last fall or earlier it began to leak from there, so I drained the tank.

Yesterday, I took a Roll-Lock and quickly removed that crud. I have a hole about .040" in dia. Looking for suggestions for a more permanent and reliable fix.

Can it be soldered? Use a solder for plumbing vs. electrical?

Should I do a quick tack weld with my mig? (I'd fill the tank with water and invert it) Anyone know how thick a stock '57 tank is? Feeling around the sending unit hole is seems almost 1/8" I'll tale a closer look at the flanges

JB weld, A 2 part liquid epoxy, Other?

Thanks
