Hello folks,
I have more than one bike and sometimes one of them won't get ridden for a long time. On my road bike with tubeless, the tires probably won't be changed out for more than a year.
Which sealant doesn't dry out, i.e. solidify into the latex skins or chunks, but instead turns into a thick even layer of goo, which can then be reconstituted with water ever so often?
This is as opposed to refilling with new sealant, which accumulates over time.
I'm thinking in particular of Slime STR, which I had in my road bike for maybe 4 years? When I took the tires off, there was a thin even layer of slimy goo, but when I added water, it dissolved again into a milky translucent color. There was only a very small amount of solidified latex which came off easily anyway.
Too bad this sealant was discontinued. I guess because it did not perform as well as some of the others in the "how big of a hole can it seal" tests. But I have never gashed my tires and usually only get thorns, so the test of sealing isn't that important to me.

They all eventually dry out. Depending on how they are stored. Heat will make them dry out faster.

Did you just completely miss my example of the Slime STR?

Did it ever work for you? Review of SLime STR below says its useless when new, its probably not any better when year old
When all you have is very thin layer of sealant it will probably not seal punctures anymore, you need some liquid stuff left for punctures. I think you should accept that you topup sealant every now and then and hopefully you wear tyre off before its time to clean and replace sealant

yes

I found Slime to be pretty useless several times, as have some of my friends who tried it. We all went back to Stan's and now Orange Seal. I am not aware of any effective sealant that does this.

I'm not aware of any sealant that has this capability.

Effective bicycle sealants either have high latex content and/or big particles in them. Latex doesn't dissolve in water.

you answered your own question.

slime, or anything that doesn't actually seal a trail puncture or have latex in an ammonia carrier

otherwise you just do bike maintenance and clean out your tires on occasion like we all do
------------------------------------------------------------------------------------------------------------------------------------
if you visit your bike every week and spin the tires and then park them 120 deg from where they were sitting
you can have a decent balanced, yet dried out, tire over time that doesn't wobble, and then add fresh sealant when you want to ride.

keep rotating the tires often on your stale unridden bikes and you'll keep them balanced to a degree, just heavier over time with dried up sealant

I've been mixing regular "tubeless" Slime with Stans (and now Orange Seal) for years now. Probably 60/40 Stans/Slime. This mixture will extend the life of the latex based sealants since the Slime doesn't dry out nearly as fast. I'm in the hot as hell desert SW so nothing stays liquid for long but this does help. Not uncommon to see 4 or 5 sealed thorn holes after a ride and it still seals a reasonble size hole....if not I have a plug kit. Still, I add new sealant often. Just no way around this fact. Climate will determine how often.

The issue is...If it won't dry it properly won't seal a puncture.

One option is to carry a small container of sealant in your bag, and if you get a puncture inject it into the tire, spin it up and pray. One way of getting by with dried out sealant. Not ideal though.

I have read that Berryman Sealr (sp?) doesn't dry out because it does not contain latex but I have not personally tested it long enough.

Over the years I have noticed that my tires will slowly start losing more pressure when my sealant has dried out. I consider this my warning sign.

You could give quadboss atv sealants a try. I think there was another "lifetime" type ATV product out there that I was considering trying but the name is escaping me.

If maintaining sealant isn't working for you they have these things called tubes that can be installed in most wheelsets that may work for you.

sounds like something Big Tube would say......

That's what I thinking, doesn't make sense to want dried sealant plugging a hole to reconstitute when the tire gets wet

Muc-Off sealant comes close. It cleans up well with water, dry or wet.

During my lastest tire replacement experiences, a quick shower with a garden hose washed most the crud off the CushCore and tire interior, leaving a few crusty barnacles on the tire bead. No peeling dried latex.

I've done some very late top offs, when I noticed my tire was flat the next day. I injected a part filled syringe of sealant, followed by a light flush of water through the same syringe (intending to rehydrate the old sealant), and the tire still holds air decently despite its age.

I don't wash the bike nor ride in the wet though.

I would rather carry 30g of sealant than 120+g of tube plus levers
