For the hull and other exposed parts, wood should first be sealed.

As sealer the consensus seems to be Clear Penetrating Epoxy Sealer. Just like Epoxy "glue" but thinner and with a longer cure time so that application is easy.

I on the other hand used a polyurethane-based mono-component primer/varnish varnish (Yachtcare G4) for my springer tug hull. Multiple thinned coats to really soak up the wood. CPES which is usually bi-component has better shelf life I suppose.

With both products hull is then stiffer.

Once hull is waterproof it can be sanded and primed for painting.

Check your local boating shop. They'll have something to offer. RC model shops also carry CPES like ZAP Z-Poxy Finishing Resin. Can also be ordered online of course.
