: Something I have noticed using balsa for surfboards is that a
: lightweight wood may end up absorbing more resin and become
: closer in weight to heavier woods. Paulownia is the best wood
: for lightweight if you can afford it and if you can even find
: it. I am building a project with fir, and although it is a pain
: in the kazoo to work with, I am noticing it does not absorb much
: glue. I'm anxious to see how it does with the epoxy. Should be
: lightweight when all said and done.

Can always seal coat porous light weight woods, after that cures it won't suck up any extra epoxy and you only barely need enough to cover the surface to seal it.
