My 1977 Fender Ps neck's (back of it) finish were fell off (some of it). Created some kind of wrinkle wrap behind my neck.. made it felt not nice, I hate it. I just sanded it yesterday and now the neck felt smooth and superb for me, although maybe I have also removed its protector coat (?). My question is: What should I do to the (back of) the neck now after I sanded it? Thank You in advance. (Im a long time lurker here, and Sorry for my english limitation).
