I know most cars have a vinyl moisture barrier between the inner door sheet metal and the interior door panel. They seem to be missing on my current project and as a result the hardboard is water damaged. I plan to replace the panels with aftermarket reproductions. I also plan to use 12 mil clear vinyl sheet to make the barriers. The barriers are usually “glued” to the door on their perimeter and around any necessary holes (handles, etc.). My question is what type adhesive to used to “glue” the clear vinyl to the door sheet metal? What I’ve seen is usually black and remains pliable.
