druxey Posted October 20, 2021 #2 Posted October 20, 2021 What exactly are you trying to waterproof? Is this for a floating model hull, or just to prepare for painting a wood surface? mtaylor 1 Quote Be sure to sign up for an epic Nelson/Trafalgar project if you would like to see it made into a TV series http://trafalgar.tv
JerryTodd Posted October 20, 2021 #3 Posted October 20, 2021 A functional hull should be glassed outside and resin inside. It need not be epoxy, polyester resin is cheaper and will do the job just fine. The glass helps "shrinkwrap" the hull so any seams that open even a little bit don't let water in. Without the cloth, the resin will just crack, water will get in and swell the wood, expanding the crack, and deforming the hull.
