[Public-list] Leaky Water Tank

[George Dinwiddie]

I don't know what the previous owner did, but the water tank is
generally formed by the two sides of the hull and a third fiberglass
wall, topped with an aluminum plate.  The aluminum plate is riveted on,
and the source of most leaks.  Sometimes there are other leaks, too.

The usual fix is to remove the top and rebed it using screws rather than
rivets.  While having the tank open, I would also fillet all the joints
and coat the inside of the tank with epoxy.

The hardest part will be the removal/replacement of furniture to gain
access.

A previous owner installed an inspection port and appears to attempt to repair it with some type of rubber or possibly hot glue.  The tank seems to be lined with some type of vinyl similar to the insides of a cooler.  Does anyone know what type of material this is?  Could it just be gel-coat or is it some type of vinyl or plastic?   If it is the latter, does anyone have any recommendations on how to repair it?
