Hi. I've decided to defret my old Danelectro, but i'm kind of confused.. I want to cover the board with epoxy, but I don't know which kind to use. When people discuss this here, they just say epoxy. Can I use any off-the-shelf two-part epoxy, or does it have to be a special kind? And how much epoxy does it usually take to cover a fingerboard? Also, while at the hardware-store, I found this "polyurethane sealant" that I thought might be good, since I know some companies use a polyurethane finish on their boards. Could anyone help me with any of this?
