I recently purchased a 1919 Gibson A1 that has some top damage due to many years of playing without a pick guard. The spruce has been hollowed some between the hard grain lines and bare wood is exposed. First question is should I try to delicately try to add some finish to the areas of bare wood or just leave it alone? Second question is if I should try to add finish, what should I use?
Any other thoughts or suggestions would be appreciated.
