Have you heard of it? I bought some for my bike tires and used it. Seems to work ok since I ran over a tack and it sealed it. But I see you can use it for vehicles... is this stuff worth it for them? Or will it make a big green boogery mess and do nothing but make me irate that I made the choice to use it...?? I removed my quote so gay, vegetarian, minority, eco-nazis who love Jesus, nuke spotted owls, vote Gore and smoke medical marijuana won't be offend.
