I'm one of those that like to believe or try products easily. Currently my two bikes have Slime filled in the inner tube. The only problem I have with the Slime is when I check the tire pressure or release air out, some slime will fly out. That stuff smells like fish. I remeber on the bottle that it says product will remain liquid in the inner tube for up to 2 years. So does the Slime product solidfy after some time?
