Mold for Polyurethane Resin?
I purchased a Polyurethane Resin mix (Part A/Part B) to create a guitar. I’m wondering though what material I can use to create the Mold? I normally work with Wood, so this is all new and exciting, but oh so confusing. Can I create a mold out of wood and coat it with a silicone spray? Do I need to use some other non-porous material?
Any insight would be excellent.
