: This is one of those queries regarding techniques/processes for
: lightweight building.
: I'm currently building a racing craft and a mate of mine is
: building a hollow timber surfboard. His plans don't call for any
: use of epoxy to seal internally and he intends to seal the
: inside surfaces by either painting or using a couple of coats of
: penetrating oil such as penetrol.
: If an internal surface needs to be sealed against water ingress but
: structural strength is not an issue, would a penetrating oil be
: a lightweight (and cheaper) alternative to a coat of expoxy?
: Thougts anybody??
: cheers

Since it's for a surfboard, I'd head over here: http://www.schweizersurf.com/ and check out the forums.

Malco occasionally posts here as well, hopefully he'll notice this thread and chime in.
