Some people substitute distilled water for some or all of the antifreeze. I believe this could not only pose freezing problems but also evaporate faster in hotter climates.

Mine seems to last a long time. I did a refill last Spring when I changed out my rear tire, and when I did another refill a few weeks ago there was still a little left in each tire. So ~ 10 months. I intended to do it at 6 months but had a long layoff and didn't touch the bike for almost 4 months.

On my 29er I put in 3 Stan's-sized scoops of homebrew for a new tire, and 2-3 scoops for a refill (more in my Ardent 2.4).

Fantastic write up, Sti!

I think a side-by-side comparison is in order:

I have my own homebrew sealant as well, but it sounds as if Marpilli's is better. I have a very simple receipe and it works, but it dries out a little faster than I would like. I use Slime for ATV's, liquid latex, and add water to the desired consistency. It has never left me stranded, but I just have to make sure it doesn't dry out. The RV fluid that he posted above will be perfect instead of the water. I don't add glitter and mine can be very thick or thin compared to the liquid you add. This is my second year using it and it seals sidewalls and everything. I got a cut in my raceking 2.2. last year and I could hear it hissing. It was a small hole and I took the tire off, did some shaking, and it sealed. It wasn't a big hole, but it worked. I think Stan's is currently better than what I'm using, but by much.

^ Exactly what caused me to seal the sidewalls / beads with rubber cement before mounting the next set of Ra-Ra's.
My first one weeped for almost a week. (post in DIY wheels & tires)

I think that's exactly what you should see on a TLR tire. The UST tubeless tires have a thicker sidewall and don't weep at all (and are heavier).

Here's a good description from the Joe's No Flats website:

What is the difference between UST tires and Tubeless Ready (TLR) tires?

It's commonly thought that the main difference is the thickness of the tires side wall and therefore TLR tires would be lighter. That is right but the reason for the difference in weight is unknown to many. The UST tires can stand alone, with no use of sealant (but the sealant gives protection from flat tires), while many TLR tires have what is called 'Wall Bleeding'- leak of air from the side wall. The reason for the difference in weight (and that UST tires can keep air with no need for sealants) is a layer of butyl that covers the inner side wall in UST tires, so it's like having a tube on the tire. Wall Bleeding requires a special solution, as most sealants found in the market do not seal the micro holes in the side wall. ... blah blah blah

Thanks guys. Shall we call our homebrew mix "a special solution" then? :lol:

I've been using homebrew now for 4 years. It does not dry out like Stan's does. 5-6 oz in a 29'er tire will last a year and a half or more. Down side is it's a mess when you pull the tire to replace, versus straight Stan's boogers usually being completely dried up when you remove a worn front tire.

Been using 1 part mold maker, 1 part Slime RV sealant and one part RV antifreeze, no glitter. This has been known as Dr. Wades Secret Sauce in the 29'er section of emptybeer for years now, if you want more info on how it got started in the SW USA, where the heat dries the ammonia out of Stan's just sitting in your tires in the garage in the summer time in a month or less.

In my experience, it works very very well in warm climates, and lasts the length of the tires life. I've found that mostly German brand tires by Schwalbe and Continental are a PIA to get the sidewalls to seal all the way up. I end up putting Mold maker in first, straight, air up, do the shake per the stans' video, lay the wheel on an empty 5 gallon bucket on each side of the wheel for 30 minutes a side with the soapy water as guidance to find all the leaks first, and I pressurize the crap out of the tire to expand it as large as possible and make the leak holes as large as possible when sealing the sidewalls up. Glitter boogers are notorious for getting hung up in there and preventing a new tire from seating the bead properly on a new install, if you don't clean and prep the rim bead area first. It's all about the attention to details with using any sealant with Stans tubeless rims and spooge of your choice.

I went and visited my Veterinarian and asked for a 60cc syringe with an offset side fitting on the bottom for the needle. I fill that up with 60cc's of Dr Wades Secret sauce homebrew mix, and pull the core on my presta valve with a stan's tool, and inject 60 cc's once the bead is seated thouroughly with the latex sealant. I also almost always coat the bead of my tires with latex sealant with an old tootbrush before putting the tire on the rim, to get a good seal and bond between rim and tire with some adhesion. Makes it a biatch to break the bead off the tire later, but it's usually a very leak free tire installation when done right, from the start. You will have to clean and prep the rim bead area of your stans' rim each time you install a new tire, but no leaks is worth it to me.

Thank you Randy. Where do you buy mold maker? Btw. my Nobby Nic is still bleeding through sidewalls.

^^^Hobby or craft stores like Michaels, or online e.g. Amazon.

Marp uses latex caulk which is much cheaper.

edit: The recommended mixing order has the following motto: "Latex Last."

Dunno how far east they go but an arts and crafts store should have it. You can usually search for a 50% off coupon for Michaels for 1 jar of latex rubber.

I will be mixing a new batch of howebrew soon I think I will be going with Randy's recipe this time given my experience with the bastid Nobby Nic.

Btw. here is a shot of sealant for trail emergencies :lol:

This idea came up while I was doing Stan's on the new bike.... has anyone tried adding a foaming agent like dish soap so that the mix starts acting like the Caffelatex stuff? I think it may be worth a shot.

Works great for me as-is. You give it a whirl and report back with the results. ;)

Would the soap break down the brew quicker?

OK, who wants to add some of this to their homebrew and see if it helps? :D

Or, do something like this: http://www.ehow.com/way_5711892_chemica ... atex_.html

But, leave the curing agent out of the mix...

I do not quite get the point of foam in the tires. You want a mix of sticky and solid particles in the sealant to get in the spot of the puncture as quickly as possible. How does foam help with that?

I have some foaming agent for my chemical photography but does it make real sense to use it?

I never understood (nor researched) the greatness of Cafe Latex. The lack centripetal force keeps my homebrew coating the area on my tire where I'm most likely to run over something anyway...

Foam so the sealant can foam up and occupy the cross sectional volume of the tire. That way the sealant gets all around the tire and rim. My own experiences with tubless conversions is the leakage from the rim. Stan's yellow tape does a good job but it isn't perfect.

innnnnteresting. one of those practice golf ball wiffle balls inside the tire would keep it foamed up nicely.

But the foaming action would also introduce more air into the solution which (I think) is why more people report inability to seal with the crappe-exlax. So maybe (like you said) the addition of fairy dust (glitter) and the bubblies it might work.

Yup... I think that's where Caffelatex fails. Add some juicy bits in it and it'll work better.

What about water wetter to make the solution wetter in addition to the anti freeze.

Waste of money since the stuff we add to most sealants already reduce the surface tension of the sealant to point of making the water wetter useless.

BTW, Redline water wetter works best with pure distilled water and a 15-20% mix of any aluminum friendly glycol-based anti-freeze (instead of the 50-50 antifreeze mix). That's the mix I've always used on my track cars to keep them cool in the desert heat.
