A few people keep saying wood flour as an additive will absorb water, but once dry wood flour is been mixed into epoxy resin I disagree- as small as those particles are, they will absorb epoxy first, and once they're saturated that's it. It's ingrained in most of us to be sensitive to the relationship between boats, wood and water ingress, so I get where the feeling comes from, but I don't think it's something to worry about in real life.
