Glitter and Tire Sealant – Does it work?

Glitter and Tire Sealant – Does it work?


I’ve had a slow leak in the rear tire of my
hardtail for months now, and I keep just pumping it up and riding it. I think we’ve all been
guilty of this type of laziness, but this leak is coming from my sidewall, which means
the tire really needs to be replaced. When I pump it up you can see air coming out
here, but shaking the sealant around plugs the hole for a while. Later today, the pressure
will be down to around 10psi if I’m lucky. So, while this tire is getting replaced no
matter what, I’m going to use this slow leak for an experiment. Many riders have mentioned
that mixing glitter into both homebrew sealants, and off the shelf brands like Stan’s can improve
their ability to seal punctures. It does sound plausible that the little grains
of glitter would get lodged in punctures and make it easier for the sealant to do its job.
Let’s see if glitter can give my Stan’s sealant an edge on stopping this slow leak. I’m going to mix some glitter in with the
sealant that’s already in my tire. This way we can’t attribute a successful outcome to
new sealant. My assumption would be that really fine dusty glitter works best, so I’ll use
this stuff. I’ll put some of these little stars in too for style points. I’ll go for a ride to get the sealant in every
little crack, and then let the bike sit for about 6 hours. By now, the tire would have usually lost a
lot of pressure, so it’s time to check. No way, did this work? I’m going to go for
another ride and then leave it until tomorrow morning, just to be extra sure. I must say I’m surprised. This tire is most
definitely holding air. In the 3 months since this leak occurred,
I have not seen this tire hold air for more than a half a day, so there’s a good chance
that it was the glitter that stopped this leak. I’m still not sold on adding glitter to sealant
as a standard procedure though. I’m guessing that it also has side effects. For the same
reasons it helps plug holes, the glitter may accumulate around other crevices inside the
tire, and cause the sealant to clump where it shouldn’t. Sealant is designed to provide
a balance of puncture resistance, longevity, and non interference with other components
like valve stems, so there’s probably a good reason that Stan’s doesn’t come premixed with
glitter. I simply don’t have the answer to this. If it does provide better flat protection,
it might be worth the payoff during a race, or a long distance trip where getting a flat
could have huge consequences. These theories are all just speculation though,
so take them for what they’re worth. In any case, it was a fun experiment which showed
that this trick just might work. Now I need to wash this glitter off myself so my wife
doesn’t get suspicious. Thanks for riding with me today and I’ll see you next time.

  1. A theory about Stan's doesn't include some glitter like stuff is that they can sell more sealant if customers lose sealant more frequently. But that's just a theory. And another comment says that they now include on one of their products.

  2. I wouldn't have thought about trying glitter 😀 For me YouTube suggested your "5 mistakes newbs make when changing flats", so perhaps the autoplay logic is slowly learning..

  3. Someone at school stabbed my tire with a knife because they thought it would be funny. My tubeless sealant actually managed to keep it together for one ride and the trip home, but later I had to melt the rubber together to get it to hold air.

  4. maybe trying out glitter on the surface of the frame for better reflections while riding during the nighttime. And pleas let us know, what youre wife says about that 🙂

  5. Nice vid! Here are two additions:
    1. Yes, it does have side effects and you will find the sealant gluing to the tire everywhere instead of staying liquid. It loses its capability to close smaller holes on the fly. I still add it if some tires are making trouble holding air.
    2. Glitter is a mess and you should ALWAYS add it outside and not where you do your other bike maintenance. You don't want to have glitter in your shocks or ball bearings, etc..

  6. I am going to give crushed walnut or cocounut shells a try. They are biodegradable, and cost less than $5 per pound. They are used as environmentally friendly sand blasting material, but it might be worth a try. It has to beat all of that plastic powder all over the place…

  7. I have noticed how easy you mount a tire on all your bike rims. Is all quality rims easier to mount tires on? I changed my rim on the rear wheel to a Mavic 721 disc (26 inch) a couple of months ago and when I mounted the tire I noticed that it was much easier. My old rim was a zzyzx and my bike is a Corratec X-vert Expert 2010.

  8. It appears to me that Stan's utilizes drafting cleaning pad material for their filler. The material is ground up gum eraser, and you may find it in art supply stores.

  9. Glittter is a pain to get rid of without any sealant, so with latex goo added to it it must stick forever.
    Have you seen this article where e*thirteen recommends using ground black pepper instead? http://reviews.mtbr.com/stans-notubes-and-ethirteen-discuss-glitter-in-tire-sealant/2
    Maybe we will se a special blend of "tubeless ready peppers" on the market soon, and some special pepper mills where you can adjust to suit all kinds of riding conditions.

  10. are you effing kidding me???? id rather handle nuclear waste than deal with glitter in my garage. They are similar too. 1000 years from now you would still find traces of either one of them still in your garage

  11. hola mi amigo. todos tus vídeos son muy buenos y aprendemos cosas nuevas. felicidades un abrazo!! este video me gusto mucho mas x los subtitulos en español. tienes muchos seguidores latinos. pero no todos hablamos inglés. me gustaría que a todos tus videos les pusieras subtitulos. para entender todo al 100. te mando un abrazo y palante que la vida es corta. 👍😄

  12. I guess one's enviromental sensibility must be inexistent to do that. At least your faible for glittler will not go unnoticed to your great grandson if he rides the same trails on which you experienced some tire damage…. good thing the "glitter stuff" in Peaty's Sealant and Stans Race Milk is bio-degradeable.

  13. Lot of 'love-and-hate' out there for the 'non-bike' version of Stans (aka – SLIME), but Slime has added finely ground rubber to their mix for years…does the same thing, actually. For $10 a quart, I'm good with Slime. A lot of the complaints against Slime would probably go away if people would learn to vigorously shake it before putting it into a tire…and then making sure they put enough in to make it actually work (most are notorious for only putting an ounce or so in…instead of basically filling it to the top of the bead on a standing tire…the way it should be)…

  14. Anything added to stans will make it work better. Why bother?
    Truckerco.com The best tire sealant out there. It not only makes the tire airtight, but seals holes – no glitter needed.
    3 times the concentration of latex, 75% less ammonia.
    Stans has a pH so high it will corrode alloy nipples. Most brands copy stans. Truckerco is way lower and is not going to dissolve rubber or aluminum.
    Best price too.
    Thanks for the review.

  15. I can't imagine the benefits of tubeless outweighs the convince of repairing a tube… You wouldn't have this sort of problem, or not as often atleast? Or am I wrong? Especially seeing as you can get a sealant filled tube…. Someone please enlighten me!

  16. Personally I would just glue some thin inner tube or use normal tire patch from the inside instead of replacing that tire.

  17. Bad news fellas Scientists Want to Ban Glitter due to the microplastics wrecking the environment. Kinda makes sense when you see all the plastic in the oceans.

  18. I've used latex paint and black pepper to seal pin holes in inner tubes that otherwise would be a pain to patch for reasons. good for post apocalyptic cycling

  19. Quick tip, and just the tip and only for the minute mind, don’t press your valve in to drop your pressure if your running slime, my hand got bamboozled in a snot like material … yuck

  20. Tubeless tires are the bane of my existence. From chipped stem holes to DIY sealant cocktails that end up creating massive layers of latex inside your tire… my god.

  21. Did you try the 'Finish Line' sealant? It should never dry out (little skeptic about the 'never' part).
    But looks good product. Thinking about getting / trying this sealant. But first looking for somebody doing a duration test…

  22. How about using that really fine sand they mix with gallons of house paint which creates a rough surface for better foot traction and covers holes in wood better.

  23. The glitter only works with cheap sealant if you get good sealant you really don't need it and it's just another job to do

  24. Back in the day, there was a sealant motocross guys were using that had glass fibers in the mix. It made the sealant a bit chunky and stringy. It got the nickname "Gorilla snot"…
