It needs to be waterproof. So that means Resorcinol, Epoxy or Polyurethane adhesive.
- Resorcinol needs to be cured at relatively high temperature, won't fill gaps and need high clamping pressure.
- Epoxy fills gaps, but doesn't like the cold and there can be problems with gluing white oak.
- Polyurethane will fill gaps to .3 mm (small, tiny really), requires clamping, but doesn't mind the cold. It has a long open time that's not dependent on temperature.
I'm still kind of up in the air about glassing the whole boat, or just taping the joints and glassing them. We'll see.
