not really - but a truss rod would
also, judge the wood you have - which to me looks very pale for an ebony and that will inform finish choice... obviously you will get a better idea of that once its smoothed out
here is my mac ebony neck - sanded to a crazy high grit with a little danish oil applied somewhere along the way
for the record - warmoth say certain woods dont require a finish. IMHO this is misleading. the fact they dont require any kind of finish doesnt mean they wont benefit from one, and i suspect they say it to make things seem easier to their customers - a large number of who are going specifically with warmoth because they want things easy!
as an example i had a Goncalo Alves neck from warmoth to work on last year. They say it requires no finish. It felt and looked dry to me, and that is how it had come from warmoth. I gave it a good soaking in danish oil, i rubbed it all back with 0000 wire wool and buffed it out with a cloth. So not a heavy finish, but something. the improvement was vast, smooth, slinky and warmer in colour... just what i really want from a 'raw' wood neck
