Repairing gavinized storage tanks.

[MapleMike]

I have a 100 gallon galvy tank that has a leak in the bottom seam.
Any suggestions on how to repair? Do you have to careful of what products you use. (food grade)
Or can it be soldered?
Thanks for your help.

Galvanized is pretty easy to solder.
Lead free solder and good flux does the trick.
I use solder I got at Bascom's and StayClean flux.
