Sealant thoughts

Mate, I have had no reason to unmount a tyre with my special seed inside so have NFI. I don't want to splooge stains all over the garage floor if I don't have to!
I suppose more glycol will prevent boogers?

Yeah I was thinking I need to up the glycol a little.

I found adding the propylene glycol caused my mix to form boogers. I don't use it anymore. Windex (for the ammonia) stops the latex going off. Whe it dries out it forms a nice even coating on the inside of the tyre which provides some puncture protection even if dry.

So can we just use cheap cloudy ammonia from Coles for $2? #notachemist
 
So I had a sealant fail tonight unfortunately.

Got a small sidewall slash and the sealant didn't seal it up.

Now, I don't want to jump to conclusions and it's no guarantee but there is a slight chance that the sealant failed because it had all dried up and I didn't have any fucking sealant in the tyre. Fuckwit.

I've always run Stan's in the past and I'm familiar with the old Stan's meteorite that forms after a period of neglect. The LBS convinced me to try Orange Seal and when I was fixing a flat today I instead found a creepy spider web situation. Is this normal for Orange Seal?

It didn't seal the flat I had, but I'm not mad, the hole basically crossed into two different postcodes.

Refreshed the sealant in my rear tyre with a new batch after I found (via a sidewall slash) that it had all dried up last ride.

Sealed the sidewall slash instantly, will be interesting to see how the slash goes with some ride induced sidewall flex.

Tweaked the recipe a bit with some more glycol.

150ml batch 22/0226:

60ml PG antifreeze
45ml demineralised water
45ml latex
1.0 teaspoon of bio glitter
2.0 teaspoon of rubber dust

Interestingly, I still haven't seen any valve stem corrosion like @wkkie had. Not sure what the difference is in this case.

Just in time for me to mix my own 1st batch next weekend. Will be picking up the stuff during the week. Can't find any rubber dust or granules anywhere, and neither do i have old tyres to sand. So going with ground coffee, dog hair, and corn starch. Will report back when i get to mixing it.

Made a litre batch using this recipe and ground coffee. Didn't have the time to buy some rubber crumbs. So will test this first. If it doesn't work, will buy some rubber crumbs and pour them in.

Haven't poured them into the tyres yet. Will do so later this evening after i come back from a ride.
