Your motor boat did not have blisters along the water line?


Yep. The blisters were in no way an "osmosis problem" since it was all
on the surface and affected only the old layers of paint.

It's Popular Science magazine - an established and
reputable publication.

Photos don't lie unless doctored in Photoshop.

The article says mercury paste was used.

That means it's available. Just because I personally don't
know where to get it is not germane to the situation at hand.

Where's your logic lately?

I don't doubt that Hg attacks Al - asked you where you get Hg paste.

Aluminum is relatively worthless for a boat hull.

All it takes to completely destroy the hull of an
aluminum hulled vessel is a handful of mercury
past smeared on it. It will begin to turn to dust within
hours, break apart and sink.


Hahahha. A handful of mercury?



A stainless steel boat is impervious to just about
anything but strong acids.


How about salt water and time?

Idiot! Paint blisters on the waterline are also called osmotic blisters.

Duh!!!

Not if there is no osmosis, at least, not by anybody who has a clue.

No osmosis? Then how on God's green Earth do you think those
little blisters formed?


Easy. Some bonehead (possibly a relative of yours) did not do the
correct surface prep on the hull. Then another person of approximately
the same mental capacity sanded through the barrier coat, allowing water
between the fiberglass and the layers of paint.

Osmotic blisters in fiberglass are a totally different thing from
blistered paint, which can occur on cars or houses...

Duh,

Blistered paint at the waterline is caused by osmosis, unless you find
those blisters filled with air.
