I won't use em'. A couple others like a front knob they make.

Yes

The slime is really high viscosity, and pretty sticky, so it pretty much coats all the interior surface of the tire in a film. It doesn't flow very well after that, and does react to air and dry a little on the surface between the inside tube air and the slime film, while the slime surface in contact with the inside of the tube remains liquid. I have had it save my rear tire from a nasty nail puncture, and I never bothered to patch the tube and it doesn't leak air. I've never had a problem with it being out of balance, even after my bike sat for the months of December and January. I'm sold on it. Granted there are going to be punctures that slime can't seal, and the slime mess will make patching the tube difficult. Those cases I'd just recommend using a replacement tube. Jeff
