Good advice Vance. I'll print that one to save.
My stainless ballast tanks are isolated from the hull for just that reason.
The bolt-on connections will get the nylon grommet treatment, and the air in/out
will have a short section of rubber hose isolating the welded thru hull and
tank bulkhead fitting.
Because it's 304L stainless, and it's been welded, I'll have to deal with
corrosion too. Not as bad as a mild steel tank but it's an issue all the
same.
Brent was talking about that Rhino coating stuff used on truck beds so I
followed some of the links and a couple of the formulations presented looked
promising.
In Seattle it's being used to coat boat hulls. I will try to investigate
that a bit when we fly into Seattle going to the convention.
The boats mentioned looked like 40 ft. trawlers which sit docked for long
periods of time. The coatings average about 3/16 inch thick and are made
specifically for that use.
I'm considering doing my hull with it. It adds sound insulation as well.
Being somewhat rubberized I wonder if it protects against electrical fields
too.
I've only seen truck beds in a couple of colors so don't know how many are
available.
I wonder how difficult it would be to spray or pour into an enclosed tank.
If I come across any thing new I'll put it out here..
