Repairing weeping FG Diesel tank
Glenn Ashmore might have said:
It will not make any difference what you do on the outside. You have a
problem that MUST be solved from the inside of the tank. When diesel
gets past the surface barrier it can migrate along the glass fiber for
several feet before it shows up outside the tank. Once the diesel gets
into the layup it will find a way out. That is the main reason why
integral fuel tanks are discouraged.
Drew has the right idea for a sloshing or brushable sealing compound for
the inside. It is NOT easy to use but that is going to be your only
solution.
Hi Glenn,
I recognize your name from, I think, the old cruising group from mid
nineties...?
Well, the tank is not integral; it was built and set into the eggcrate, so I
can't fix from outside without removing it. So, you're right, it must be fixed
from inside.
As posted as reply to Drew, resin is polyester, not epoxy; hopefully this
sloshing ariplane stuff will work.
Nice website - hell of a boat. I have a lot of respect for you builders - you
build em - I'll sail 'em years later! I'm an engineer by trade; hate sticky
itchy stuff, but don't mind heat and grease! Always liked the saildrive - had
one on an O'Day 28 years ago.
Hope to see you cruising in the Eastern Caribbean someday...
Good sailing,
John
