How to avoid glue in the grain around the neck joint?

[ADFinlayson]

As the subject says, something that has plagued every build of mine is glue squeeze out getting into the grain around the neck joint (in particular the endgrain on between the horns on the body) which I find practically impossible to sand out? I've read recommendations before to oil the body prior to glueing the neck in, but that involves getting all the sanding, staining and finishing done before glueing the neck in and it hasn't worked well for me.

Should I be grain-filling the body and neck tenon (up to but not including the glueing surface) prior to glue up? If so, what would you use to grain fill Limba? If it's useful, for the build in question I'm planning to use minwax wipe-on gloss poly to finish the guitar in question.

I leave extra wood around the pocket and then finish the carve/sanding after gluing the neck in.
