A couple of days ago I took the plunge and defretted my p-clone. The defretting went great, only one tiny chip (but thats why God invented super-glue). So anyways, I need to know a few things: 1) For the fret slots, I was thinking of shoving 1/32 inch plastic in there instead of wood since I can get the plastic for free (I have a ROP class). But my teacher suggested something that might be easier; if I mask the wood around the fret slots, I can fill the slots with gel coat (resin). This sounds pretty cool seeing as it would be easier, and I can make my fret slots any color I want. Would there be any drawbacks to using gel coat INSTEAD of wood, arcylic, or that wood paste crap? 2) The second question is your opinion on the finish. I want your complete biased opinion on wood finish, epoxy finish, poly urethane finish, tung oil, ect...if it helps, it is a rosewood fingerboard. I'm leaning toward the poly urethane finish because its so readily available through my plastics ROP, but I can change that if it really is terrible for the sound. Thank you all for your advice!
