Hi Steve, Is this a GRP tank with a lid that is fastened all around the top perimeter?
Common in the old days was to use a "food grade" gelcoat rolled on the inside of fabricated tanks. It's probably called "potable water" gelcoat these days. That would explain the cracks/crazing that you see. Otherwise gelcoat might be a good solution anyhow (pun intended).
BTW Is this your theme song? https://www.youtube.com/watch?v=bzmFXw0yFaM Cheers, Russ Sweet 35 mk-1 At 05:59 PM 11/07/2017, you wrote:
Need some help/advice from some more experienced C&C people. I am rebuilding a '73 30 MK1 project boat, that was started a few years ago by another person and abandoned along the way. I am focused on the settee area right now. First, I think I can get the mold cleaned out of the water tank, but it looks like there are some fine cracks in the bottom. Is there something that I can do to seal it up (paint, liner, ?) that would be safe for potable water?
