Use this, not Fastack
Without writing on a disseration on gluing your tires, please don't use Fastack. I saw more than one catastrophic failure result from this glue, which sticks well but tends to fail all at once with no warning (it is more brittle than rubberized glues). I think that ClubRider is saying the same thing when he says use a rubberized glue (like this Conti glue), just wanted to clarify. Among glues, I find this one to be the hardest to screw up, and therefore recommend it to all my tubie-riding friends. Make sure you know how to glue tires before you trust your work.
