I know of at least 2 folks who have made their own Bocote necks, and I don't think either one of them used any finish on it.
As a matter of fact, I remember them commenting on how nice the Bocote felt by itself.
If you want to put something on it, I would recommend Tru-Oil, a Polymerized Linseed oil that a LOT of people really like for the 'feel' on their necks. It has driers in it so it cures in a few hours, and you can re-coat twice a day.
Tung Oil cures soft, Tru-Oil cures hard.
You'll find it at most all gun shops and WalMarts gun section.
PS, I would never wipe anything on one of my necks without really knowing how it is going to react first, especially a pricey neck like that.
I bet it's gorgeous!
PPS, You might want to e-mail Jason Lollar at Lollar Guitars, he is one of the two who I know have made several Bocote necks, and is a very friendly guy to converse with.
