What do you use to spread glue into the Domino mortises?

For me, it depends on the size of the Domino. For all but the smallest (4-5) I use the little paddle that is on the back of the handle of the brush I found a year or so ago. It's one of those silicone bristle things that you can let the glue dry on. It's too wide for the little ones though. I usually split a piece off of a wooden shim, with a razor knife, and just throw it away after.
I have used acid brushes too, and still do sometimes. I always have a box of them in a drawer for whatever comes up. I cut the bristles to about half length for glue spreading.
 
That Rangate stuff is for real Chuck. I believe they manufacture adhesive delivery systems.
 
Popsicle sticks. Work great. Throw them away.
Get a box cheap on Amazon.

(No, they don't come with the popsicle attached. Besides, I'm on a diet.)

I have only done doors and face frames, no big panel glue ups.  But I use the 'Sedge' method, my 'fingah'...
 
I also use popsicle sticks, also bamboo skewers.

Dip/roll Domino in glue, insert in mortise.

I use a scrape of wood or paper plate for the “puddle” of glue.

I use flux brushes cut in width and length to fit the application.
 
I just use a scrap piece of ply maybe 8"x8" squirt some tight bond on it roll my dominos in it get both sides wet and pount it in the slot. for the edges, I have some of those rubber type reusable brushed brush the glue on the edges put it all together
 
We ordered Pei Wei last night and they gave us a bunch of these small round sticks in the bag. I took one look and said hmm I can use these for stirring paint but now I read this and figure they could also work good for spreading glue in the domino mortise.  I dint measure them but they were pretty small not sure if they will work for 4mm but 5mm and up they should.  You should be able to reuse them a bunch of times as long as you wipe the glue off after. 
 
I use dowels, but the process is similar.  I use glue/acid flux brushes from Harbor Freight.  You can get them directly from H-F  $2.50 for 36 brushes..  I use them and then dispose of them.  I suppose you could wash them clean, but I don't bother.

YOu can also get these from Amazon.com, but at more than twice the price.

I run a bead of glue on the piece as usual. Right across the open mortises (works best if the bead is at the edge of the mortise).  Allowing the glue to start running down the side of the mortise. This step is nothing extra since I already need to run the glue bead.

Then use an acid / flux brush to spread the bead. While doing this stop at each mortise and twirl the brush inside the mortise. That will pick up the glue that is running into it and spread it around both sides in the mortise.

Then I put the dominos into the mortise. Use the brush again to spread glue on the half of the domino that is now sticking out of the mortise. Most of the time there is enough glue on the piece where it squeezed out of the mortise to just pick it from around the domino.

      For most general assembly I don't worry about putting glue on both the mortise and the domino. I don't get too picky about perfectly covering the domino evenly. Unless the rest of the gluing surface is small and the domino will be doing a lot of the actual holding. Just get some glue on it. I take more care if it is needed.

I normally don't glue Dominos, I use them dry for alignment and for shear strength where glue does little to improve on their performance in that direction.

But when I am applying glue most times I use either a silicone glue brush/paddle or an acid brush.
 
I would mention that I use Woodworkers III as it has the longest open time (and is a bit stronger) of all the Woodworkers like of glues.

I used to use silicone brush.  If I am doing smaller projects, I still do.  However on larger glue ups like cabinets I will do what Simon does but no brush.  I found that in warmer weather even with Titebond III it just sets up way too fast.  I lay down glue bead down middle of board, and one side edge of mortise.  Then hit other side of domino with glue and tap it in... plenty of coverage and glue spread.  Then I'll glue a bead on mating surface and on both edges of exposed domino.  By the time I can connect the pieces, gravity has helped the glue run down domino faces and voila.  The key that helped me do this more precisely, the BabeBot from FastCap.  It is a Dominoer's dream because the glue flow is infinitely more controllable than with the regular GluBot.

Yes, Gluebot  / Babybot and Lee Valley Cabinet (Maker's) Glue 2002 GF.  Really good stuff. Color is tan, long enough open time, thicker viscosity than Tight Bond (great when something is vertical), strong bond.

I seldom use Dominos for alignment only as loose tenons but if I did I can't see why they have to be glued, it simply doesn't make sense. When used as a structural loose tenon I use the dip and fit method simply because it is so much faster.

+1, if I even put glue in them.
