The trick is to learn how to operate a tube of glue 
But seriously, your glue will last MUCH longer if you squeeze the tube until the glue is at the end before placing the cap back on. That way, there won't be any air in the tube to cause the glue to cure. It's a simple step that makes a big difference, but hardly anyone does it.

Just figured I'd dump out the sealant if I had to, and clean/dry that section. I'd prefer a plug

I do carry a tube on all rides. May just buy the micro plugs as I go more tubeless.

Don't". Glue less patches don't work well. Don't waste your time and money. Buy a regular patch kit and keep it in your seat bag.

I carry glueless patches....and a tube of glue.
If the glue in the tube is not dried out, I use the glue in the tube and the glueless patch.
If it's dried out, I just use the glueless patch and repatch when I get home.
So far, so good.

As a plastics and rubber chemist let me say I don't think that glue cures in the tube. It just dries out. It contains natural rubber which bonds to the rubber in the patch and the tube during curing brought on by crosslinking chemicals. In that way it bridges between the tube and the patch making the bond. I'm pretty sure the curing chemicals are already in the patch and the rubber cement solvent just makes them available throughout the three part structure: tube rubber-cement rubber-patch rubber.
I get enough flats that problems like glue and tubes getting old is never an issue.
EDIT: Come to think about it, if the glue is drying out, it seems like it would help to have less air in the tube.

Sorry but I just don't buy into planning to repair tubes on the road. Patched tubes really need to cure over a short length of time to get a strong bond. Road bike tubes are so small, just carry a few. Yes, have a patch kit for that really unlucky day, but don't make patching tubes on the road a habit. It just isn't worth the time and aggravation.
I carry three tubes, three CO2s and a patch kit, most recently glueless. Everything fits easily in my back jersey pocket. The whole idea is to finish the ride or if really unlucky, just to make it home. My method has always allowed that. If I absolutely have to patch the tube on the road (four punctures), the glueless patch is quick and easy. When I get home, there is plenty of time for glued repairs.

I hate to tell you but the glue (rubber cement) for glued patches has no effect on glueless patches. They don't have any curing agent in/on them and won't bond to the tire through the rubber cement. That is the reason they provide an "iffy" fix, they bond by contact adhesive, not curing to the tube. Rubber cement isn't strong enough an adhesive to improve that bond. I can't believe that method you describe has ever worked.

The real trick would be for the kit makers to package the stuff properly. Anybody who's going to use the amount in a typical tube in less than a month is going to be buying in bulk, so for the rest of us, why not some tiny single-use blisters of cement? Just enough in each for one patch job, so no need to re-seal anything.

I use glueless patches to get me home. At home I replace the glueless with a regular patch.
If you have opened the glue tube in a patch kit you could find yourself with a dry glue tube just when you need it.

For tubeless (and tubular) tires that don't seal due to puncture size, I spread superglue on the tire, put on the preglued tube patch onto the tire, wait, inflate. I don't carry tubes anymore.

robabeatle, I assume you're talking about spreading super glue on the inside of the tire, but which pre glued tube patches are you using?

No, the outside of the tire is where the glue and patch is applied. When you get a puncture that sealant (Orange Seal, FTW) won't clot due to size, follow what I stated above. The patch will wear off but it provides the infrastructure for a clot to form. I found this trick watching a youtube video where it is done on a tubular, in the rain. the patches are Slime Scabs. Other brands might work better or worse.

Ah, very interesting. That sounds great to me- beats taking the tire off. I am currently using Orange Seal in the road bike tire. I may switch to Stan's since I use Stan's on the mountain bike

I have used the Rema vulcanizing patch kits. My seatbag contains a brand new, unpatched tube in addition to patch kit. You never know when you might get more than one flat. Sometimes my flat repairs don't turn out so well, but I've gotten better with practice.
