Carpet Glue

Hi All,
I'm getting ready to install carpets into my Sprite. Most of the carpets
will be removable, however I am planning to glue down some of the
carpet. For example: Frame rails and inner rear wheel arches. What have
you guys found to be the best glue for this application ? And where can
I buy it ?
FYI, I'm using Wilton 3 carpet (Dark Green) that has a black rubberized
backing.
Thanks,
