Hi Bruce,

Thanks for the link. I went to the site and it wasn't clear to me (no
pun intended) which of the listed products are the ones to which you
are referring. Let me take a stab at it.

I think I can identify:
- the insulator as NAUTICOAT ISC-909/ISB-910 - INSULATOR "A" AND "B,"
- the sealer as NAUTICOAT PSP-906 - POLYESTER SEALER/TOPCOAT, and
- the polyurethane as NAUTICOAT PG-N-SERIES - HIGH SOLIDS GLOSS LINEAR
POLYURETHANE TOPCOATS SP.

Can you confirm that these are the products that you used?

Also did you spray them on brush them on? I ask because I don't have
the spraying capability.

Many thanks.

and it is untouched after a year in Florida. I expect to get 5 years

out of the system...maybe more if I am diligent in the upkeep.

Most people opt for varnish over polyurethane because of price.
All the
high dollar boats have a insulator/sealer/polyurethane topcoat
system.
Stuff is beautiful and last forever.



I'm not familiar with the insulator/sealer/polyurethane system but
it
sounds interesting.

However, if you walk into your local finish supplier or chandler's
and
you pick up a quart of polyurethane off the shelf it is still a
varnish.

Over the years, heck centuries, varnish has had many definitions.
It's
mostly defined by it's make up during that time period.

Today it's usually accepted that a varnish is a combination of

Curing oils, be it linseed, tung, or these days, a modified soy
oil,

Resins, in the old days these would have been natural resins,
amber,
rosin, etc. Today they are synthetic. In other words plastic.

A Carrier/thinner. Usually mineral spirits.

Polyurethane shares the basic ingredients as the lower octane stuff
but
it's resins form a stronger mechanical bond then the lesser
varnishes so
it is kind of set off on it's own.

From a woodworking perspective, oddly enough, this is not necessary
a
good thing.
