I'll do the experiment. Phone would y'all like me to do it? I have a bucket of tubes to patch now. I've been using Elmer's rubber cement for a few years now. In fact, my oldest bottle congealed, and I had to toss it. But it's so cheap, I feel I'm ahead of the game.

I try to keep an unopened tube of glue in my on-the-bike patch kit. That way, I'll know it's likely to be there and not dried out.
