SEAL-nots
Tube-ass sealant.. needs much refining.. by many many miles. Dryout.. the empty promises. Lots of it is really JUNK.
Yes.. I expect ALLOT. Why not? 'Condomes' inside the rubber is history.. seal-NOT is all that's slowing this advancement down. You argue...
trying running that condome rubber near low flat.. what happens..
Here's a thought/idea.. free to the community.. for the intellect types. All half dozen or so... LOL. Not me.. by miles.
Ok... DRY sealant. Say WTF he sez... ?? Combo of particle sizes w some making adhere to bead gap et al. Combo of materials.... you get the plan. Do doubt.. a viable route. Yet.. no refill route.. which is what this current junk has going for it.......
Where is... a good chemist when/where one needs them....

I’m sure it would work. Similar to dehydrated water...just add water.

That said, sealant is a complex problem that is kind of difficult to solve. The latex in the sealant needs to be kept in very small particles until it needs to agglomerated together to make large particles to fill a hole. That’s not an easy task to solve. Essentially, you have a can of paint that is in constant contact with air and the issue is to keep the paint from drying until you absolutely need it to.
The glycol in the sealant are meant to do this but there are issues. It keeps the latex dispersed but it is also soluble in the rubber of the tire. The air pressure in the tire also drives the glycol to dissolve into and through the rubber (Le Chatelier’s Principle). It’s a difficult problem to solve. Changing the solvent might work but I suspect the shelf life would suffer.
A dry sealant probably wouldn’t work because there is nothing to disperse the sealant where it is needed. Belts in the tire are only partially successful...tube tires are susceptible to punctures with belts. We’ve had pneumatic tires for 150 years now and no one has developed a foolproof system.
Bottom line, you just have to live with the problems. There is no magic bullet to fix it.

As for the rest of the post - or what little sense I can make of it: I really don't understand the complaint, so am supposing it is user error. Most sealant works fine when used as recommended.

Tubeless tire systems are not sold properly to the riding public. The sealant needs to be topped off every so often as it does dry out. What we have found at the shop is removal of the old sealant and cleaning out the tire and rim every two years gains maximum results. Whenever someone inquires about tubeless setups I tell them if they have a serious problem with flats or a serious need to run low tire pressures or need to save weight for performance issues, and understand that tubeless requires more "regular maintenance" than tubed tires, then they are the right choice.
For the everyday common rider tubeless is a not so good idea.

Once you have a process down, maintenance is pretty easy; a syringe and valve stems that'll pass the syringe will make life so much easier.

I top up and fill up with a piece of tube connected to a 60ml syringe. I still have to remove the core for it. This could cause leaking or crack the seal in theory.

The syringe may or may not be good depending how chunky the chunkulator in the formula is and how much you want to get into the tire. I've been fine using the tube that comes on the top of the Orange Seal bottle. Carrying the stem remover in the bag and taking out the valve is not onerous. They're now selling valve caps that have the remover built in. The Stan's Dart also has a remover built in. So does the top of a Slime bottle, for Schraeder.
It seems like you should be able to top up the sealant by stabbing a big needle right into your tire but I haven't been brave enough to try it :-D I recall a post where someone repaired the latex tube in their tubular tire that way.

16ga needle is about the largest you can realistically get. I think I've seen some 8 and 10ga specialty, reusable ones. Anyway, I've drawn up betadine with a 16 and you've got to go slow and it's a pain.
Sealant is about a million times thicker than that. Stan's is pretty thin. It might work in an emergency but I would be worried.
Better would be a valve stem with a branch. Think of the port on the side of a Foley catheter. Set that up with a luer lock and go. Of course this would be wider than the valve hole, so it would need to be an extension, like something for deep rims. It could be done though. Maybe.

What do you mean by this? Some sort of connection to the valve stem that allows you to keep the valve core in place? So you don't have to deflate the tire to top up? If it doesn't gum up, it should work. I haven't seen such a thing though.

There is one system, Milkit (sp?), that allows you to insert/remove sealant without deflating the tire. You still have to remove the core, but there's some type of flappy valve at the base of the valve stem that'll hold the air pressure without the core in place.

In college, we had a drink called "The Wisconsin Depth Charge": a shot of whiskey, dropped (shot glass and all) right into a tall mug of beer, and then chugged all at once.
Somehow, I know I drank some of these, but I don't recall any specifics. Hmm.

I wouldn't jump to the conclusion that English is a second language for this poster. I've had plenty of college students (native English speakers) whose writing skills are only slightly better. If you are older than about 40 years, you might be surprised by high school standards in some states.
As for the rest of the post - or what little sense I can make of it: I really don't understand the complaint, so am supposing it is user error. Most sealant works fine when used as recommended.

Hmmm. I am scarcely blameless in this regard.
On that subject, I agree with cycommute. One additional issue is that compressed air often has moisture in it. So a dry sealant that depended upon low humidity to be able to "flow" would get more gummed up with every topping off of the air pressure.

I'm coming to the conclusion that if a person measures cycling in months and years, tubeless might not be for them. I measure everything in miles.
My syringes of choice, I just use some of my massive coil of 1/4" vinyl tubing left over from the aquarium days for attaching to the stem. The 100ml are fantastic.
