I've owned and played a few vintage Fenders where the rosewood finger board looks like it's been polished to a shine. Since I wasn't the original owner or know the exact history of these old Fenders, I never knew if this was a natural result of extensive playing or if someone along the line had applied some type of hard finish to the fingerboard. Recently, I've noticed that a boutique bass builder (Alleva-Coppolo) has achieved the same deep shiny polished look on the fingerboards of his new instruments. I was wondering if anyone here has any idea how to make a new rosewood fingerboard get that shiny look. FWIW, my rosewood fingerboards are made of Brazilian. I know that Alleva-Coppolo uses a buffing machine but I heard there's some secrets/tricks to the process. Thanks.
