I have a custom shop relic and down by the cowboy chord area, the back of the sanded down neck is just a little tiny bit rough... not so it will give splinters or anything lol - it isn't that bad - but enough to sort of affect the grip down there. As opposed to the middle of the neck which is baby butt smooth. Will this just play itself smooth in time and I should leave it alone? Or is there an approved treatment that won't devalue the guitar - meaning should I hit it with 0000 steel wool and/or put some tung oil varnish or something on it? I don't want to over-react and mess up the guitar, especially if this is reasonably common and it will just "wear in".
