Adding finish to a rosewood fretboard ?

[mildew]

I really like the feel of the finished maple fingerboard on my Soapie.

Im thinking about adding finish to the rosewood fretboard of my Singlecut.

Is there a technical reason that non maple fretboards dont normally have finish on them?

I could get my local luthier to do it but if its really easy ill do it myself - what is the process?

Rosewood is naturally oily and resistant to fungus and wood rot which makes it unnecessary to finish. However it CAN be finished even though those same natural oils make it difficult. Some rickenbackers have finished rosewood fretboards. Maybe test drive one of those first and see if that it something that really appeals to you before you do something super drastic and regret it.
