    Does anybody have a source (or recommendation) for the vinyl sheet used to seal doors and keep moisture from the interior in a Dino 308 GT4?

    In disassembling my doors I found two different liners... one is a clear plastic sheet and the other is a gray colored vinyl sheet with a fine fabric-like texture on one side. I suspect the latter is OEM, but that's only a guess.

    I'm looking for confirmation and for where to source the material. Thanks in advance!

    As long as they do the job it doesn't "really" matter what color they are. If you really want the same color you can find vinyl sheeting in rolls you can cut yourself. I'm sure it's way cheaper than a Ferrari part.

    Mine had long lost its sheeting so I re-did both sides when I did my window motors.


    This is what I used:

    I buy heavy plastic sheeting and using aerosol glue attach it to door. Then with razor blade cut off excess to shape.

    great to see advice from Rifledriver as it seemed like he took a break (and this board would suck without his recommendations based on LT experience)

    Use a High Performance Damp Proof Course Membrane, the "high performance" references an "upgraded" polyethylene material meaning usually not made from recycled resins. It will have more tear resistance, especially over time, and as a result you can likely reuse it in the future should you have to remove it again. Usually 4 or 5mil, so slightly thinner than the 6mil clear polyethylene vapour barrier material more commonly available. Building supply stores carry the high performance stuff, used for concrete work hence why more tear resistant. I think some suppliers have it available in Rosso Corsa color...

    I buy grey vinyl shower curtains from Amazon and cut to fit, they're very close to what the originals look like.
