lining water tanks
 

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

system sold he

Potable water approved epoxies (NSF 61 approvals) are common in
water treatment facilities. Most, if not all, NSF 61 approvals are
only for tanks greater than 1000 gallons (easier to pass and
from vendors point of view, gets rid of the small jobs). That
said, many folks will use them on tanks less than 1000 gallons for
personal use.
