Take a look at exterior Luan ply... Just built two dingy's for the
grand kids... One out of marine fir at $55 a sheet and the other out of
mostly Luan at $9 a sheet... The Luan boat lots easier to finish
because it is smooth to begin with... By the time the plywood is
coated with epoxy and then painted the plywood can't tell if it is on a
boat or a house... The fir boat is taking as long to finish the hull
as it took to build because the fir (**** pine) is so rough, and is
taking more dollars in epoxy, filler, etc..
