So I've got a structure I've recently built from foam board and was wondering what you guys use to coat it to add some durability? I've used a fast setting resin like onyx fast and it worked great but was extremely thin and cracks after too much sanding. I've heard a million things from plasti-dip to watered down Elmer's glue. The end goal is to have a sandable surface that can be primed, painted, and molded.
