In fairness, if the LBS stocked regular Orange Seal, it’s what I would’ve used. I’ll empty the Stan’s and see if I can get my hands on regular Orange. Hell, by then I’ll have tried all the major players except Silca and Muc-Off in some form. 
Stan’s Race is like Silca, you pour into the tire.
Orange Seal regular you can use syringe, and you have to stay on top of adding sealant once a month especially during the warmer months. Due to the coating action, I will check within a day or two of setting up a new tire, and often have to add sealant after the first couple of rides.

In the Pacific NW do you ride day after day in 90F weather? Because here in Sacramento valley those are typical day temps for month after month after month, and once a month I absolutely need to use the dipstick to check sealant levels in the tires.
My recent experience:
I’ve had too much trouble with Conti GP5000 S TR tires. I’ve had three flats this race season. Once in a crit so I could get wheel and jump back in, but twice in road races, which caused me to DNF. Super frustrating. Apparently these tires are a bit thinner than the GP5000 TL (the first edition of the tires), so while they’re a bit faster, they’re more prone to punctures.
I’m now switching things up and going all-in to avoid more punctures. Going to try Stan’s Race sealant, Vittoria Corsa Controls for more puncture protection, and Vittoria Air-Liner tire inserts. I’m also going to start bringing a Dynaplug kit and CO2 with me on race day in hopes I can get a shot of air into the tire when there’s a lull to stay in the race rather than dropping out entirely.
To be fair to the Contis, all the punctures have sealed and have just needed more air to get back up to pressure. I’m hoping to avoid flats entirely in the first place, though.

Josh Porter talked a little about the different sealants on his Marginal Gains Podcast and said Orange Seal Regular is pretty similar to Stan’s Race Sealant while Orange Endurance is more like regular Stan’s. Having used all of them at various times, that’s been my own experience. I’ve had good success with both brands.
More recently I did order the new Silca sealant. I mounted a brand new set of the current gen (not the older ones) Schwalbe Pro One’s in 30 Enve 3.4ARs. I set up tubeless around Christmas and then took them to Maui in January 2022 for a two week camp. Maui is pretty rough on tires with a lot of bits of lava rock on the road as well as spots with glass and other debris (especially on the West Maui Loop). I got several punctures during the two weeks on the rear tire, pretty much right in middle of the contact patch, but they sealed up with Stan’s Race Sealant.
Since then I did a number of road rides locally where the conditions are much gentler on tires. Not a ton miles since weather was bad and riding indoors, but probably about 300 - 400 miles or so. No further flats or leaks that I could tell. Last week I decided to change out the sealant. I popped the bead and wiped out any remaining Stan’s and then put a scoop and half of Silca’s new sealant in. Reinflated and headed out. About 40 miles into the ride I heard a leak from the rear but it sealed almost immediately. I carried on and about 10 miles later, after going over a small rough patch of pavement that was in a small dip in the road, a big air hissing noise. This time a lot of sealant sprayed out. I didn’t stop immediately and wanted to see what would happen, so I slowed but kept riding. The hissing stopped. I gave it a few more pedal strokes and then pulled over to check. The tire had sealed, again with what looked like a puncture mid-tread/contact patch, but interestingly there was a big blob of sealant on the outside of the tire that was already hard/rubbery. The tire was a bit soft so I topped it back up with a CO2 and figured, what the heck, and road on. The tire held up for the next 50 miles. I couldn’t “feel” the blob of sealant as I rode but interestingly it was still mostly there when I got home 50 miles later.
This past weekend I did a 110 mile ride on Saturday but switched out wheelsets as I don’t trust those Pro One’s anymore. I’ve got both a set up GP 5000 S TR’s and some Pirelli’s on order. The Pro One’s don’t seem to be very robust as this is the most punctures I’ve had with a road tube tire (ran GP5000’s and Specialized 2Bliss prior). My initial experience with Silca Sealant seems to suggest it works well but will continue to test it on gravel and XC as well.

Sounds a bit like my experience with the Schwalbe Pro One’s. Maybe the Pirelli P Zero TLR is a better way to go?? I ordered a set of the 28s to try.

I am using regular Stan’s with KOM injector. I don’t want to mess with pouring, so I will go Orange for my next setup (or sooner if this one sucks).
Unless the Bontrager sealant is awesome in which case I’ll use that since I can get it right down the street.
I’m using Stan’s. Here in the UK, it takes over a year to dry out (I only once had that happen), and I’ve never had the clumps forming either. However, at some point, most of the latex is gone from the solution, and it sort of separates. I usually switch tyres about once a year, and then top up sealant every couple of months. (Usually before long rides/events, or when the bike hasn’t been used over winter etc.) I do use quite a bit of sealant though, about 60ml in a new tyre, with a 30ml top-up a few weeks later, and then maybe after 4 months.
I had 1-2 punctures in road tyres that would seal, but only hold lowish pressure (30-40 psi). Its deffo enough to get you home, but would then leak bit more overnight and need more air in the morning. A different sealant might work better, but its good enough for me, and I like the ease of using Stans in all tyres.

Last night I rode for at least 1 hour with a nail in tire, found this when arriving home:
Only lost 4psi during the ride! Roubaix Pro are tough tires!!!
Before going to bed I put some bacon in the tire, and puncture side down so that Orange Seal could do its job. Woke up this morning to this:
Bacon that I’m planning to cut, and an Orange Seal “stalactite.” Even better was the Orange Seal “silly putty” left on the garage floor that I peeled off:
Maybe I should take the tire off and use one of my tubeless patches to seal this from the inside. Opinions?

I was going to try a Park Patch on the inside of my tubeless tyre that wouldn’t seal after it got a p’ture but I’ve no idea how effective it would be.
I haven’t read it all but this guide talks about patching them How to repair a punctured tubeless tyre | Step-by-step guide to plugging, patching and sewing tyres - BikeRadar
I’ve patched other tires, works well. I’m using the Hutchinson Rep’Air tubeless patch kit. Goes inside the tire.

I’ve used the Hutchinson kit once on a pair of Gravelking SKs. Seemed to work very well if you follow the application instructions.
I’ve probably patched 5 tubeless tires using the Hutchinson Rep’Air kit, always worked well.
I’m going to take the tire off and patch it.

The road apocalypse rider formerly known as bbarrera is now WindWarrior. Maybe I should change my forum name again?
Embarrassed to admit this, before last night’s ride the rear tire was 20psi. And thought of you and your intro to tubeless woes, because its only the 4th ride on this brand new wheel and tubeless install. So I was thinking “kurse of Kurt” and maybe I needed to have the Specialized factory tape replaced.
Anyways, before the ride I pumped it back up to 69psi and spun it around to check for wires/tacks/nails/screws/goatheads. Maybe I was a little to hasty in checking the tire, because last night I put 69psi after the bacon repair, and woke up to 67psi and a sealant mess on the floor. So I think the tape and valve are fine. Think its time to visit the optometrist for another eye exam.

I don’t know why I always forget the change. Old habits die hard I guess? No one ever calls me nash031. 
@nash031 I’m starting to believe I rode the full 2 hours with the nail.

As a lighter rider I’m wondering if I can get away with running Vittoria Corsa Speeds as an ‘everyday’ tyre on my fast bike. I flat about once a year on tubes, and don’t do crazy miles. I also love the feel of Corsas. Anybody using them like this or have feedback?
