We mortals can not compress a liquid.
So adding any glue to both pieces is not needed
UNLESS you do not have a perfect glue joint. And are using Epoxy.

PUT some glue (you pick) on one piece & press it to the piece your
going to glue it to!-PULL apart and check for dry spots!
THAT means the joint is not perfect!

Fix the joint!
Then apply glue to only one part!
DO not put so much glue that it seeps out all over the joint!

Without great glue joints -your guitars will not be great!

The folks who build wooden airplanes say that the way to be sure you got glue someplace is to put it there. I generally worry less about a bit of glue squeeze out than I do about a poor joint from lack of glue. Glue is cheap.

On some joints I put glue on only one piece but then rub the other one to make sure it is fully wetted before clamping it. I don't worry about squeeze out either and in fact more often then not I am tossing away an old bottle of Titebond or batch of Hide Glue.

I have removed many fret boards and even bridges where they obviously applied glue to one side only and there are dry spots all over the joint. Some of these guitars have been well over 100 years old so it's probably 'good enough' even when they don't fit perfectly but then most of us don't accept that.

Here’s one that came through the shop earlier this year. It definitely did not last 100 years before failing

I do glue bridges by using glue on both surfaces but here is what is more important
Good glue surface contact is paramount and proper clamp pressure
but it still is good to apply a thin coat to both surfaces.

so my question is this if your going to spend 50 hours building a guitar why cut corners?

I apply glue to both surfaces on Bridges and necks on the other joints a good glue coverage just so you see some squeeze out

I also apply a thin coat to both surfaces. I am also picky about well-fit joints.

doing repairs & making guitars -I've never had a well made glue joint let go!

Just remember we can not compress a liquid!
So lots of bleed out is
glue wasted &&& maybe not allowing the pieces to join
completely.

Just me experience talking!

If you can score some Asian Mystery Glue on the dark web no matter how you use it the joint will withstand a thermonuclear attack and still be intact in an archeological dig centuries later.

A mid-70s Martin bridge I reglued had surprisingly little glue evidence. 'Course, that's probably why it came off. But still, I was surprised at Martin, though mid-70s was not their heyday.
