Default 2 part varnish vs. 1 part

That's OK. You can make it up to the group later.

Um......Voting is stupid and we should just bomb the rest of the world
into dust so that we can build cheap condos and more marinas for our
boats.

As I understand it, he's not going to have bare wood in any event.


True but that's been adressed already.

Nah, a heat gun & scraper will take the stuff off, but it's a royal
PITA and everything else Max says is true in spades. Polyurethane is
for furniture, preferably furniture that doesn't get a lot of use. In
my experience it looks great for about a week but it is subject to
crazing & fogging and it cannot be touched up at all.... you gotta
take it all off and put it all back on.


I think i am leaning towards the Epifanes option here. I need it
hard. I'll try not o drag it on the beach but sometimes it happens,
not to mention the trailer.

Furthermore (and this is the real kicker) many polyurethane finishes
will not harden properly when laid on over epoxy. I've had this
problem before and it's very frustrating. Manufacturers act like
they've never heard it before but they've known for years. If any
urethane or poly paint/varnish doesn't specifically say that it is
compatible with epoxy primers & undercoats, DON'T put it on over
epoxy!


Will do.

What you may consider is to do the last laminating over your wood with
a peel ply, then lay on another coat of epoxy with UV inhibitor. MAS &
West both make them and they are both beautiful & tough finishes. They
can be touched up at will. Should be just fine with nothing over it,
unless you're going to leave the boat lay in the sun all season. Then
you might want to put some cheap varnish over it.... it will look
yellow, but the varnish will come off before the epoxy, like a
sacrificial layer


This is a maybe but i really want that glassy look on the boat. I
don't know if i can get that with a peel ply with cheap varnish over
the top.

Thanks,
Bill
