Yes, I could call/ write Stan, but you guys are more fun. I took off a Hutch Python Air lite to change rims. The same tire would not seal on a new rim because there was dried sealant on the bead, etc. Anyway to get this stuff off so that I have a nice clean seal? I had to put in a tube (sorry about the foul language) because there were stands and clumps on the bead.
