Fingerboard care

[Bob Faulkner]

Ken, I just wanted to bounce this off you. I've read where some people have had problems with their ebony fingerboards splitting or cracking after a period of time (not Smith basses). While I'm not overly concerned I'll have this problem on my Smith fretless, I wanted to get your recommendations on how best to care for my lined fretless ebony.

Up to now all I've really done is hit it with some Smith Pro Formula Polish from time to time to remove the finger crud and ebony dust that builds up. Do I need to be oiling it or anything as well? If so what do you recommend?
