You're not saying that all latex based sealants are basically the same?TobinHatesYou wrote:MikeD wrote: ↑Thu Oct 06, 2022 3:40 pm
Orange Seal regular is good and I've used it for a long time. I've had sealing problems with the endurance version though. What I don't like about Orange Seal is that you have to shake the bottle vigorously and that makes the sealant foam up. It's almost impossible to measure out the right amount of sealant when it's foamed. You could use weight though. OS is not CO2 compatible either. Those two issues are addressed by Milkit sealant, which I'm using now. It doesn’t require shaking and is CO2 compatible and is injectable through the valve. I can't vouch for how good it seals flats yet, as compared to OS nor how fast it dries out. No flats with it yet. Reviews are good.
I weigh my sealant. It's easy to do. Orange Seal is just as CO2 compatible as pretty much anything else. They're almost all water and propylene glycol based. If using CO2, inflated with the valve at 12 o'clock. Release all the CO2 when you get home.
Another thing about OS that I've observed is that it uses shiny metal particles to help plug holes. These small flakes of metal separate out which is probably why you need to shake the bottle vigorously before application. Obviously I'm not shaking the bottle enough because there was a bunch in the measuring cup left when I used up a bottle. Milkit uses small, light particles that stay in suspension. I think that's a lot better because those particles in OS aren't going to stay in suspension inside your tire either. If the constituents in OS need to be mixed when it's already in your tire for it to seal, then that's maybe an issue too, although tire rotation may be sufficient to mix it up.
I'm not saying that OS isn't good; just saying that I'd like something better. Maybe Milkit is it, or maybe not. However, I'm not happy with OS Endurance though. I've had too many small leaks that didn't seal fast enough/left a puddle of sealant on the garage floor and a mess on my bike. I think that if you've had it in your tire for months, even though it's still liquid, at that point it doesn't seal very well anymore. A fresh addition of new Endurance sealant into the tire sealed it almost instantly (a thorn puncture).
