I am trying to complete a project P-bass for an upcoming gig in Cancun. I have a Mighty-mite p-bass Fender licensed neck which appears to be unfinished. I like the feel of it as is but I have concerns about the humidity factor and warpage. What type of finish should I apply that would be smooth and unfinished feeling but still offer protection from weather change, etc? Application instructions would be most helpful as well. I tried a search but did not come up with much directly addressing this. Thanks in advance for your help.
