I need some advice on what to do with my Carvin LB75f I just got off the bay. It has an ebony fingerboard. I would like to string it with roundwounds, so I guess I need to apply some marine-grade epoxy, right? If the answer to the above question is yes, how do I do it? How many layers do I need to apply? Just out of curiosity, how long would the bass last without any epoxy strung with roundwounds?
