Hi Don

My personal choice would be 2 part epoxy if you can still get it in your
neck of the woods.... I built a 15 foot tunnel boat that I had a Honda
motorcycle engine in at first with 2 jet drives.... I later converted it to
a 60hp outboard. Lots of elbows in that tunnel. The 2 part epoxy is tough
to beat...

Regards
Steve

I'm constructing a 10" tunnel hull and am at the point where I need to
seal/finish the interior of the hull before putting the decking on. The
boat is not going to be left out in the elements or used in sal****er but
will be stored indoors when not used.
My question to the group is this, can I use a good grade of spar varnish
to
seal the interior or would the epoxy encapsulation be the better choice?
(I
plan on using epoxy and fiberglass on the hull exterior).

Any brands of varnish or epoxy to suggest?
Any suggestions?

Thanks in advance
Don
