The only thing about tanks is that you cant see where there might be trouble

Was the foam damp??
The top looks fine but there might be corrosion where you cant see it. down along the sides and the bottom. Places that if wet never dry out.

The other thing ... How hard is it to get to your tanks once the boat is back together ?? It would be a pain in the a$$ to rip her apart again cause a tank is leaking and it needs to be replaced.
