Stan's sometimes gets some negative feedback. It's not as good as they proclaim! It doesn't have glitter in it! The Bontrager Sealant does!
Well, even I think of switching to Orange after all the negative hype, but the truth is that Stans works for me. I've had it seal 8...yes 8 punctures in one ride alone.
A couple weeks ago I was out in a semi-remote part of central Oregon. Of course I picked up a goat head when I was less than half way through my Century. And of course before I could resists pulling it out of my tire, I did pull it out. Yikes the sealant was oozing quickly. Argh, I didn't want to deal with installing a tube for this ride!! So, I rubbed some dirt on it and rode off hoping it would seal and I could forget about it.
I made it home hours later, tire full of air. That was 2-3 weeks ago and it's still holding the same air.
If you need flashy, sparkling glitter in your life, they make a sealant for that. They make snow globes with it too. But the truth is, Stans Still Works as it did when it first was introduced!
Stan's is the best for a flat. I don't ride without it. If you are fixing a flat in the garage or on the road in the middle of nowhere, have some Stan's on hand.
Easily handles what rocks and gravel throw at it. I've never been stranded in the hinterlands using this sealant.
I do not recommend drinking this sealant - but it works great in tires. I started with Stans years ago and tried others lately - none of which worked as well or easily as Stans - so I am back!
