This may sound like heresy to some but I used a belt sander to rough fair
outside and for all the inside. I knocked off the edges on the outside and
then faired to the second stage with a ROS. Final stage was power
longboard. Inside I sprayed with Dykum blue machinist ink diluted with
alcohol. Then put some rubber under the wear plate on the belt sander to
give it some curve and sanded on the diagonal until there was only a thin
stripe of blue along the seams. Inside was not completely fair but it was
good enough for the glass to lay tight.

Started out with 1 1/8" thick by 1 3/4" wide strips and ended up with a
pretty even 1" thick.

I understand the need to plane and sand the outer side of the hull of
wood strip built boats so that it is fair and smooth. You'd
definately want it as smooth as possible to facilitate passage through
the water.

But doing the same to the interior makes me wonder. Fairing the
interior reduces the thickness of the wood strips. Maybe this isn't a
big deal, and it also has the benefit of reducing weight. But I just
wondered.

If you aren't going to show the boat, wouldn't it make sense to just
clean it up and apply the fiberglass?
