I am looking for the right adhesive…
I make block ice in stainless steel cans, the cans are filled with tap water and then this can goes into brine water.
that freezes up to -20 celcius.

the cans are welded but over time the saltwater eats up the welding and it starts leaking, i was thinking of also adding some kind of adhesive from the inside where the seem is .
what adhesive do you recommend?
