Am making a new helm
station to hold, instruments, switches etc and a new gear
lever on the stb side, made a mock up first, and am now building out of 12mm marine
ply, all joins were mitred to make a strong join, have glued (Epiglue, 2 part epoxy
glue) and screwed with 40mm stainless screws.but no screws on angled joins, I was going to sand everything then coat with a 2 pack penetrating epoxy
inside and out, prime then paint
white. My question is will the joins be strong enough and not crack or should I put a layer of glass over all joins and fill and feather out if yes fibre or cloth?
