Just sprayed the vinyl sealer and it *mostly* went well. I'm going to hit the few spots that have buildup but overall I think it's pretty clean. ... Except for a small part of the neck.

I taped off the neck and didn't notice that a piece of it completely covered a piece of the wood no bigger than my thumbnail. I was able to hit it with one layer of vinyl sealer before my rattle can ran out. I am hoping to avoid buying a whole can of this stuff to add a few layers. Would gently feathering fine sandpaper to blend the border of the low spot be a good idea or create more trouble than it's worth? Any recommendations or suggestions would be appreciated. Pictures:
