A while ago, after flatting the 32 Supreme on my commuter Sam, I
mentioned trying Joe's tire sealant as extra protection in the rear.

Last few weeks I have been needing to top off air a lot in that tire,
and figured the sealant was doing its job - turning what would have
been a flat into a slow leak and holding some pressure so I can get
home.

Today I decided to change out the tube and see what was going on in
there. Well, it's a mess. White sticky stuff everywhere - all over the
outside of the tube and the inside of the tire. Washing the tire
didn't work so I put an old Pasela on in the meantime.

Verdict is mixed - I avoided a roadside repair and was able to keep
rolling until the weekend. OTOH, what a mess.
Not sure if I should keep using the tire. Which brings up the next
question, what to replace it with? At this point I'm thinking about
another Supreme. But what size? A 28 for the from and do the Sheldon
shuffle, or a 35 for the rear? Or just put the 32 back on when it
dries?

Anyone know how to get sealant off a tire?

This sort of mess is my Big Pet Peeve about sealants. Nothing worse on
a ride to find that in addition to the hassle of replacing a tube your
tire is full of messy slime, now contaminated with roadside sand.
Beside, it really doesn't take long anyway to swap out a flat tube and
get back onto the road if you carry a decent pump.

*Another* pet peeve: people who jump at a FS item, ask a lot of
questions, say "YES!", they want the item, then disappear for good.
Me, I've backed out of sale commitments as a buyer a few times by
politely asking the seller if he or she minds if I do so and
expressing my willingness to come through if he or she does mind.

Over and out.

That sticky stuff is supposedly good for you, sealing leaks in the tire.

Judging from the write-up on their web site, it looks as though you are
meant to leave the goo in place, adding to it from time to time, every
6-12 mo. http://www.no-flats.com/products.php?categid=1

The sealant is meant to stay in the tube and stay off of the tire. Jay
is talking of a standard tire-and-tube combination.

And if you get a puncture through the tire and tube, isn't it reasonable
to expect the sealant to come out the hole in the tube and fill up the
inside of the tire? Which is exactly what happened!

Yes there is: when the user fills up the tire/tube with sealant from
what looks like a shave bomb, thinks the tire is too low, asks you to
pump a little more air into the tire, and you do, and when you take off
the pump shave foam sprays like a fountain out the tire valve all over
like a little volcano science project covering the tire, the rim, the
spokes and anyone within range with foam. That's plenty worse.

To which I reply:

There is something worse.

What's worse is working at a bike shop and fixing a customer's flat with Slime in it (it *still* boggles my mind that people bring flats to a bike shop...)  Inevitably this occurs on a busy day when you have five other things going on.  You pull the tube off and lo and behold, slime.  At this point, you look down to realize that your shoes, socks, legs, shorts, hands, forearms and the front of your shirt are covered with the vile stuff, not to mention the inside of the tire.  Often times you get the warning of the green valve cap, but usually these are long gone.

Jay:

No comment on the sealant, have never used. To your question:

"But what size? A 28 for the from and do the Sheldon
shuffle, or a 35 for the rear? Or just put the 32 back on when it
dries?"

If your commute is tough on tires, I'd be hesitant to go 28 mm, even
with a good tire. Maybe put the 32 on the front and a 35 on the
rear.

I don't know about Joe's, but Slime never really dries, it continues
to ooze out the micro-holes forever. Not a design flaw, that's just
how it works. Latex based sealant (Stan's, Caffelatex) actually dry
and plug the hole. But they need to be re-filled with fresh liquid
every three-six months, so that's their downside. Joe's says to
re-fill every six to 12 months, so it might be latex based.

Verdict: Don't put any of that crap in your tires.
