I took the patch kit from the bike's bag, roughed up the tube area, and then found that the little tube of rubber cement was empty. I took the patch kit from the other bike and the little tube of rubber cement was empty as well. Each kit had been used once, and the cap was not loose on either rubber cement tube.

I borrowed a bottle of rubber cement from a neighbor and sealed the tire, but apparently the solvent in rubber cement vaporizes very easily. That's a nice attribute when you have to wait while it dries to apply the patch, but not so good when you go to use a patch kit and it's useless.

So, I guess get a patch kit that doesn't use rubber cement, or be aware that your patch kit may be useless. I'm sure other folks have noticed this but I haven't encountered the problem before so either someone is stealing my little bits of rubber cement or it's something that should be noted.
