JB weld to repair hot water tank?

[SoCalStreamr]

Its wierd to me that everyone is into JB Weld instead of Marine Tex. Must be because it is more common. Is JB Weld safer for food-grade water sources than Marine Tex or something? If not Marine Tex is a superior product to JB Weld in my experience. I have repaired radiators, engine blocks and more with Marine Tex. Marine Tex will fix almost anything properly applied and is as easy to work with as JB Weld.

If Marine Tex wont fix it, it needs to be welded. I order Marine Tex from West Marine.

I used a steel can lid to reinforce one section and that worked great, but it gave out in another area where the aluminum weld has failed. If that doesn't work, I think I'm going to order a new unit. I'm not sure I could remove enough of the JB weld down in the crack to make the weld trustworthy. I'll keep you posted.

A 38 year old water heater, should simply be replaced.

A patch is always a patch, and if that fails on a trip, you will invent more bad words.

Replace it and be done with the issue.

Amen klattu. I believe "Mickey Mouse" repairs () more often than not, give "Mickey Mouse" results (). Time spend trying to repair it could be better spent replacing it... and you won't be spending the dollars on quick-fix products.

Just my thoughts...

Do it once, do it right! Less money, frustration, aggravation, and often less time!! JMHO from experience.
