Have been slowly raising the funds to start a SeaTour 15 yost build and finally got to buy the marine plywood, 16' (few lil knots) WRC, titebond III, and some sinew. I asked about tung oil at the hardware store and got quite an earful about how it won't protect and how Florida's humidity will be absorbed by the wood and it'll get heavier with time... He said epoxy IS the only way to go.
I want to protect the wood enough for at least 5-6 yrs w/o breaking the bank. Epoxy is too smelly/toxic (a friend volunteered his garage for this and I don't wanna smell up his place/children). Other stuff is probably just as smelly anyway...

From your experience, what has worked well for you in the past that is inexpensive yet reliable (kind of an oxymoron there...)? FYI I looked at/thought of Waterlox marine tung oil ($$$), Epifanes($$), Spirit Line's tung($$), 100% tung oil from The Home Co.($), Interlux Goldspar($), Zar??(?)...

Would 1qt suffice for the frame and can any be succesfully used to also coat the skin (again inexpensively yet reliably)?

BTW, Happy father's day to all dads here! Buyin' the wood was my Father's Day treat :D
