240z Inner Door Trim Panel

[240 in OZ]

Hey All

After seeing this ebay auction:

http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&rd=1&item=7917549896&category=33696

Id like to ask if the plastic sheeting shown on these items is correct and original? I originally thought that the weather sheet was attached to the inner metal skin of the door panel itself, but after seeing this auction and also finding remenants of plastic sheeting on my door trim panels under the upper edge lip trim, I am starting to question my thoughts/understandings.

Is it possible that the sheeting was on the trims themselves AND on the door panels?

Regards

It's possible that there was plastic on the panels. I never saw it, but have seen remnants like you mention. There definitely was a moisture barrier on the inner surface of the door shell.

The plastic is reminiscent of the plastic bag that new panels come in.

Out of all the cars that I've restored, I've always seen the vapor barrier attached to the door and not the panel.

Could it be that some ingenous person at some time figured that the main purpose of the plastic is to protect the door panel (it isn't) and attached it to it?

FYI, the vapor barrier is attached to the door panel to seal the plenum inside the door from the interior, and keep the moisture and dirt inside there. Door panels are typically attached via single point clips and as such are not "air tight" to the door panel. By attaching the vapor barrier to the door panel it keeps the air / moisture in the door and not just protect the door panel.

As an idea to protect the door panel, it is a definite plus, but not the best. I've seen some door panels with a shellac coating on the back to protect them from the moisture, that, in my opinion is much better for moisture protection than the plastic (for the door panel).
