We use a 10′ diameter x 10′ tall galvanized culvert for potable water storage. It has begun to form pin hole leaks, and we would like some help on coatings, to seal the leaks and extend the life, that are compatible with consumable water. The tank is exterior and goes through several freeze thaw cycles each winter. Plastic liners are available but get torn up from ice, so we would prefer not to use one.
Any suggestions would be appreciated.
Thank you,
Joe Odell

There are some coatings that can be sprayed or painted on for an application as you describe. The better ones are available through industrial suppliers and I don't have any links to give you, but you might explore such areas as food processing, marine anti-corrosion coatings, etc.
I've been around some used in industry, but they involved sandblasting, etc.
I'm assuming you don't want to spend a lot of dough or you'd just replace the tank (which you may have to do anyway).
I've also used some stuff for coating the inside of gas tanks when they get pinhole links, but You're probably going to need 2 or 3 gallons at least of something like that and I don't know if it would be safe with potable water.
I confess to not being a big help, but maybe get you headed in a helpful direction....
If you don't get much response, send a post to "Junkhound." He's always got some novel and inexpensive solutions.

I have a good article on fixing up rusted out tanks by lining the inside in concrete. it works, is cheap and doesnt contaminate the water.
I cant try to scan and send if your interested, just let me know.
