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

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.

You refer to Portland cement, I presume?
