I told you I wasn't going to be pedantic - and gave you a clue, very
useful in your clueless case. Yet you refused to follow it.

So, here's just one link among many:

http://www.yachtsurvey.com/my_wet_hull.htm

I await your erudition as to why what I'm going to do is worse than
leaving it ashore in an oven for a couple of years...


Comeuppance my aching arse! LOL.

That article says NOTHING about how this thick, sticky substance is supposed
to rise to the outside surface of the laminate all by it's little ole self.
One must wonder why it says nothing about that? Well, perhaps because it
defeats the whole stupid theory about hosing down the outside surface of the
laminate which does nothing more than closing the barn door after the
livestock has escaped.

The fact is that the fluid that pops up the blisters has increased in volume
due to osmosis. This increase in volume because of increased water content
is what creates the pressure that creates the blisters. The very same water
that got into the laminate over the years through osmotic action will get
out of the laminate via diffusion and evaporation over the months provided
there is a low enough humidity environment outside the stored hull. If you
could store the hull in low earth orbit, for example it would take all of a
week to completely dry it of moisture as the moisture would actually 'boil'
out due not only to humidity differences but to pressure differences.
Storing the boat in Florida where the relative humidity hovers around
70-100% would make it a very long and probably useless process. Someplace
near or above the arctic circle at a high altitude would be ten times more
effective due to low humidity around 10%.

But, finding such a vacuum chamber as outer space on earth would be
cost-prohibitive so the only alternative is a very low humidity environment
(cold baby cold like in the arctic) so the relative low humidity contained
in the air serves to hasten the drying process. The sticky or hard substance
that remains in the laminate after the water that got there via osmosis
diffuses away is of no or little consequence once the barrier coat is put on
as an effective barrier coat stops osmosis so it will remain a hard or stick
substance that will no longer absorb water to pop up more blisters.

The dumb method of hosing the surface down with water might be effective if
one could drill millions of tiny holes into the laminate to release all the
oozing sticky chemicals but just hosing down the outside of the hull with no
way for the water to penetrate relies solely on existing holes and oozing
chemicals. Sorry, but this is not effective in a total drying of the hull.

If you want to patent an effective blister elimination method, Skippy, and
get rich then patent a system and a tool that penetrates the entire bottom
to about the middle of the laminate with millions of tiny holes then hose it
down frequently with water to wash off the oozing chemicals then dip the
hull in an acetone bath several times and let it bleed the chemicals again
then dip the hull in some water-impermeable resin so it wicks into the
millions of holes and solidifies the hull then barrier coat it and you would
have an effective, relatively quick but permanent repair.

The method you are enamored of now is a half-assed method at best. Pie in
the sky.

Ah Willie-boy, you just keep going on and on amazing us with your
brilliance and great knowledge... Unfortunately all of it is wrong.

Perhaps because you are getting on in years you are simply parroting
information which was thought to have been be correct years ago has
been totally superceded by better and more accurate information over
the now.

But, exactly like the people who insisted for centuries that because
the sun rose in the east and set in the west that it was obvious that
the sun orbited the earth you are totally wrong. I can hear their
arguments even now - "It stands to reason"... :"Everybody knows"....
"You don't understand physics"... all the old faithful arguments used
by ignorant people over the years. You see Willie-boy you are neither
intelligent nor original. Just ignorant.

Cheers,
