Don't use FG or resin. It won't work. Ships use steel water tanks almost
exclusively. The tanks are plastered with cement. It lasts for years and it
keeps the water sweet.

I have steel water tanks on my boat (www.jassira.com) that are still solid
but the insides are a bit mucky and rusty. My plan is to line the inside
with glass fiber. . I have woven cloth, polyester resin, gel coat and a
waxing agent that when mixed to the gel coat allows it to air dry. I had
thought of using epoxy resin, which I understand is more water resistant,
but when I went to buy some, it was suggested that epoxy might leach nasty
things into the water..... I only want to do the job once so what resin
should I be using...
Thanks for your help
