I have never used Fastack because I have always been told that it does not have the same reuse properties as the real thing. I would be very nervous about riding on a tire I replaced on the road if I were using Fastack.
It works great of car trim, though.

Addenda: Recently a warning was published either by a
USCF mechanic or by Continental to the effect that the
newest formula of Fastack will unbond the rim tape
from Continental tires. Be forewarned.
