I need to repair a leaking seam on my fiberglass water tank. Somewhere I

only fiberglass resin be used inside a fresh water tank? krj

You can certainly do this as long as best practices are followed, so you
don't wind up with epoxy residues in your water. This is nothing to mess
around with though.

There's an article about it here, under Boat Repair and Restoration:

Think carefully about how much this project is really going to cost
you in labor and materials, even your own labor. To really do it right
is a lot of work. An "expensive" polyethylene tank may start to look
cheap. Bladder-style tanks can be a good solution too.
