Here's some info from the Avon site about repairing a flat tire. It should only be used in a temporary manner just to get you home and then deal with the consequences.
Question...
What about fix-O-Flat sprays. Is it cool? Will it throw a tire out of balance. What about that green mung tire fix?
Avon reply...
Avon does not recommend the use of any liquid material to repair or prevent flats. This can cause degradation of the inner liner along with corrosion to the wheel. It is also nasty stuff for the dealer to have to clean off during a tire change. This type of temporary repair can adversely affect the tire's material layers and hide damage to the tire caused by a nail or other object. And most importantly the use of these products can create a heavy spot where it adheres to the inner liner of the tire and throw the tire "out of balance" which will cause handling problems. This could even cause tire failure and an accident if the sealant fails.
