I purchased a roll of Butyl adhesive (that's what the factory uses) from a local auto body supply company. It sticks like crazy on the door, but I had issues getting a secure bond on some smaller areas of the vapor barrier. I think that the process of removing the barrier, and the old Butyl, slightly delaminated the surface of the barrier. If I ever need to do this again, I'll order new vapor barriers (about $35 each) to insure clean bonding surface.
PS: A quick way to check your vapor barrier is to remove the Puddle Light and stick your finger inside. The panel will be wet in that location if the barrier is leaking.
