here in Turkey, we might have marine epoxy and we might not... I want to add a superhard fnish to a fretless rosewood fingerboard, and have heard, of course, about this stuff. What I need to know is this: is this epoxy used for sticking boats together, or is it some kind of varnish? The answer to this question will help me locate the material locally. And can anyone help me with some tips for application? Do you apply it proud and sand down, or do you have to get it right first time? Many thanks.
