Does a commerical domino glue applicator exist?

The rockler glue set has a tip that fits well in dominos. The silicone finger also applies glue wel to the dominos themselves. The box even mentions domino use.

Edit- I prefer just squirting glue in the mortise and using the glue paddles to spread glue: Glue paddles
 
I put some glue on a waxed paper plate, dip/roll the domino in the glue then install in mortise.

To much glue in the mortise, you risk blowing out the other side of the work piece out if the mortise was made on the tight setting.

One of my guys blew the face sheets off a piece of 3/4” plywood last week driving dominos into the mortises, his comment to me—“oh, now I see what you meant”.

The Lamello 175550 Minicol Glue Bottle works well, although is a little pricey.  Or, you could go with Lamello's  Lamello LK-3 (1 Gallon) Glue System with pistol - No. 502003 - $795.00 which is they're (low end!) pressurized system.
 
Cool if something like this is developed for dominoes -- controlled glue dispensing:

I feel really low tech. I just use a trimmed off solder brush. I buy about 100 in a package. I shorten the bristles and apply glue. I toss each brush after it’s used. There is no clean up and the trimmed brush seems to get the right amount of glue in the right places.
 
There usually isn’t much need to glue the Domino in. I often don’t use any glue in the mortise and just a dab on the Dom. Surface area of the the little tenons is way les than the joint itself.

No glue in the mortise? If this indeed is a proven method, I would use it! Can anyone else confirm about this practice?

I would love to simplify my gluing up procedures with the dominoes, as a recent project (carcase with middle shelf plus vertical divider (in dadoes), a back panel in blind grooves, and lots of dominoes) took me a while to figure out how to get it glued up before anything froze up. It would have been easier if I had had only the dominoes to apply glue.

In case you only use them for alignment (or you need them floating) then use them dry.
Used as structural support for corners of cabinet doors, picture frames and such warrants gluing them (as they often increase the glued joint surface by a relevant magnitude). You also have the option to glue only one side in should you want later destruction free disassembly, but then you might need other means of holding the joint together (connectors, screws, ...).

Use a slower binding glue? Pre-glue in one side of the dominos so there are less mortices to process?
 
I guess for long-grain to long-grain glue-ups when you use them as alignment not gluing is ok.... but for other joints glue does give a lot more strength. And I'm not sure where but I some some testing done where gluing both surfaces gave a lot stronger joint that just gluing just the domino or mortise.
 
I never put glue in the mortise. I’ve built outdoor park benches, king size bed, cabinets, boxes , etc  this way and I’ve never had a joint come loose.

I just brush Titebond III on the tenon and tap it in. Ditto on the other end. I don’t load up on the glue. A modest slathering is adequate.

Too much glue can trigger a hydraulic pressure blow out if the mortise walls are thin.

If I’m using an oily wood like Ipe, I’ll clean the mortises with naphtha (outside) just before gluing the tenon in. I use a cotton cloth wrapped around a tongue depressor to swab out the mortise.

Same here...I found some narrow 1/4" wide solder brushes that work well. I don't like the wider 1/2" versions because the bristles splay out.

I already use white glue or old brown glue for the more complex glue-up jobs.

Pre-gluing is occasionally done (on the endgrain mortises), but I should do more of that. Thanks for the reminder.
 
The lowest tech glue applicators I use are free: every time I eat breakfast at A&W, I pick up a few of the wooden stirrers for use as glue spreaders.

Another option is Titebond III.  I contacted the people at Titebond on a complex gluing project and that's what they recommended to use for a longer open time.

I use tooth brushes. you can carve up the head to match what you want. I trimmed a brush down to just 1 row. This way it fits in the domino slot. easy to clean.
