I recently bought a Lakland Skyline fretless bass off of craigslist. It's really in great condition, & I'd like to keep it that way. I find myself a little apprehensive to use it, because I prefer Rotosound SS Swingbass 66 strings, & I'd hate to leave permanent grooves in the rosewood fretboard. Does anyone know of a luthier that would apply epoxy to the fretboard in the central OH area? I'm about 50 miles from Columbus & 45 from Athens, OH. I rather not do it myself. I am fully prepared to contact different shops, but, the guy I bought it from was told by one of the most reputable shops in town that epoxying the fretboard is COMPLETELY unnecessary, leaving me to believe, they don't have any experience doing such a thing. Can I apply boiled linseed oil, etc to the board to darken it, knowing that it will be sealed under epoxy?
