Marine Grade Plywood vs. Reclaimed Fir Planks for Carriage Doors
I'm going to be building some carriage doors and have a couple of options for the inset panel. I can use a sheet of marine grade fir plywood or I can use reclaimed 1x6 t&g fir hardwood planks. The doors will be painted. Aesthetics aside, which choice will fare better given my location about 50 yards from the beach in Southern California?
Thanks for your advice.
