Think of it this way, have any of your unlaquered fretboards (just about anything rosewood or ebony that isn't a Ric) been damaged by your sweating? Those are just oiled.
Yup, that EB-0 I just got from ebay - I pulled the frets out with my nails
Seriously, rosewood is a quite different wood - and has it´s own ´oiliness´. I´m not at all an experienced finisher,
and can´t really compare it to mahogany in correct technical terms.
Naturally, any wood can, by the right craftsman, be oiled OR painted or whatever to look great.
My point was that open pores is not my cup of tea, wether its an oil or laquer finish.
I´ve seen many good looking oil basses, and some not so good looking project basses with oil right on top
of bare wood.
