they had a segment on slime on todays american lemans program. The demonstrator had a small tire that was treat with slime and he poke it with a ice pick and you could see the hole turn green from the slime. Is that how it looks when slime is used on a flat tire?

 

That's how it looks. Wait until you take the tire off to repair it. The whole inside of the tire will be gooped up w/ the stuff. Nasty, but sometimes you just gotta do what you gotta do.

 

I read that it's pretty nasty inside but I guess it's better then driving home on a flat.
