I was going to offer my front tire, but as I thought about the pros and cons of intentionally riding around with a bad front tire, I remembered that I Slimed that tire shortly after installing it. (Very slow leak that I couldn't find...) So I guess that's out.
If you don't get enough takers, I could be persuaded to install an old rear Pilot GT that I have sitting in the garage. But if I go thorough that trouble, I'm probably going to go for the max effect, and attempt the 10mm hole that this stuff claims it will plug. I figure to make it realistic, I'll grab a lag bolt with 10mm width of threads and run it into the tire...
