I need to remove the plastic weather / vapor barrier from my doors to replace some broken door handles. What should I use to re-seal the plastic to the truck? I have never had good luck with just pushing it back on, after 10 years most of what was holding it is no longer tacky.

Ideally I would like to use what GM would use. I would like to avoid using some generic messy aerosol based spray adhesive if I can help it.

I can't tell you what does work, but I can tell you that I've tried contact cement and double-stick tape with little to no success.

You could try a local auto glass place. They usually have barrier film on hand.

Or try Napa and see if they have the barrier film.

Be sure and clean all surface areas of the door with Denatured alcohol to remove any adhesive and then apply a Butyl Sealing rope then the Film..:thumb:

I've been an all around mechanic for a little while. Well 40 years. The best & easiest way to reattach those old door wind dam, dust barrier , moisture barrier and a host of other names is a hot glue gun. It bonds instantly , it can be removed without tearing up the plastic barrier. A quick wipe down with a clean rag or paper towel. Make short 1 inch beads pressing down plastic as you go.

I use a silicone caulk. I use silicone a lot for such things (mild adhesive) as it can always be peeled back off. Unlike anything with latex or poly, it won't harden and thus does not create a permanent bond if you need to remove it later. I actually remove my vapor barrier about every 5 years so I can lube all the parts in the door, from the window stuff to the lock and handle stuff. I also use clear packing tape on many parts of the vapor barrier. In the Vegas heat, never an issue removing it later. Meaning this dry heat doesn't dry out the tape or the silicone.

Emblem and trim adhesive or headliner aerosol. Both are contact cements. Apply to both barrier and door, allow to tack, place together, done.
I just use the headliner aerosol anymore.
