Great sealant replenesher
I put a bunch of the actual sealant in my tire when mounting it, but somehow managed to have a leak around the valve stem and lost most of the liquid. This filled it back up and now no more leak.

Does it’s job
This is the messier sealant I have ever use. But that is the only bad thing I can think off. This sealant seals everything you throw at. You just need to make sure you top it off every 3 months and clean the whole tire every 6 months. I’m not coming back to any other brand.

The best, but more expensive and wasteful in 4oz
Silca sealant is the only one I've found that reliably seals 28c road tires at 80 psi. This refill easily injects through the valve stem. The 4oz size is convenient for road and gravel tires, but you'd need 2 bottles for MTB tires. I wish Amazon had the 32oz refill size so I didn't need to throw away so many 4oz bottles and it would be more cost effective.

Great product
Silca Ultimate sealant is the best! I use this as a quarterly top up and it keeps me rolling without issues.

Great product
Used the product to seal Rene Herse tires. Which is no small feat as they are cotton sidewall tires. Amazing as the tire holds correct pressure without air for going on two weeks. Don't have any punctures yet so I will update later.

A Must for Silca Users
If you're using Silca Ultimate tire sealant, you have to get the replenisher. It extends changing out sealent up to a year plus and it works. Absolutely worth it..

Don't waste your time and money
Sealant dried up in 2 weeks. Couldn't stop a pin prick hole. Do NOT believe the hype. Going back to Orange Seal.

The Ultimate with some significant usability caveats.
I've used this latex with fibers for the last 11 months. I've gotten no flats so far. Prior to using this, I had roughly 4-6 flats per year. This stuff works. Its amazing. It was difficult to install because the fibers kept sealing the injection syringe port. I may need to install new tubes and sealant soon because slowly, gradually this stuff is sealing up the tire valve so it's very slow to put air in the tires. It's truly amazingly tenacious. I guess the qu3stion is if you really need something this effective or if regular old latex would be good enough and much less hassle. If you want the ultimate resistance to flats, this is it. For me it's worth it. I ride on bumpy roads and got a LOT of pinch flats. Its reduced my rate of flats to zero. If you go 2 years with out a flat, then maybe go with the normal latex.

Ultimate Sealant
It’s a little over priced but in the long term worth the money. If you don’t like fixing punchers in bad weather or before going for a ride it just works perfectly.
