I’ve got to replace both rear door vapor barriers and am expecting the worst, so I need to stock up.
What is the black goo used to attach the vapor barriers to the door and create a water proof seal?

The black goo is butyl adhesive. It is available on line. I bought a tube of it that was caulking gun size. I used it on the drivers door panel that someone else had been into. They had removed the original butyl and applied butyl tape. It doesn't work very well IMO. That's why I peeled it off and used the liquid butyl. I've had to go back in there again and it worked just like the original. Stretch it a little, cut it with a knife, then stick it back together when done. It's essentially self healing.
