Water tank coating - is there a "safe" epoxy?

Are there any "safe" (FDA approved?) coatings - epoxy, or otherwise for potable water tanks? I have an integral fiberglass tank, and it developed a few cracks in the bottom - I'd like to fill those with something that isn't going to make water any worse than it already is for all the slime

Also, is 5200 sealer appropriate to seal tank covers? What else is there that is "food-grade"?

I've seen the one in a first link - it seems to be not specific to boat water tanks and only approved in very specific circumstances. The other one might work - but it is not an epoxy.

I wonder if there is anything from boating specific sites? I'd rather make sure someone used the product on a boat.

Actually, what you should be looking at is CeramKote 54. Their website is located here. The people who made my boat use it for coating the internal fiberglass potable water tank.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

I would NOT seal a water tank lid with 5200, unless you expect never get back in there without the help of some critically placed C4 charges. When they say permanent they mean just that.
