Sorry to bust up the Slime hate, but I've had good luck with it. It says it's not for bead leaks, but in my experience it works just fine. I've never had a problem with it being out of balance. I use it on any tire/wheel that has a slow leaker that I can't otherwise seem to find, and it works well. Agree though, it does pit wheels, but what do I care, it's on the inside where I don't see it anyway.
