Inner Door Liners and Moisture Barriers

[DD (CA)]

In sharing BTDT with Gene and others, since I'm about to tackle reassembly of a door or two...

When tearing down, was met with plastic sheet held by spotty black e-tape just behind door cards. Figured there was no way this was stock. Once finding bubblewrap glued to inner door skin, was convinced entirely this was Captn Smoke's doing...

But, Gene tells me he too had plastic moisture barrier.

So, we're both wondering what y'all have found under there and what, if any, is commonly used now? I'll likely use the thin metal stuff from dynamat , "dynaplate" but it is expensive... wow. It will block moisture, make the door frame more rigid, insulate (by sealing off door), quiet and still fit under the cards. It's like wide ass aluminum tape basically. Would think I could get similar from an HVAC store.

I bet a buncha you haven't sealed the doors...

My car has a slightly different flavour of plastic sheeting on the door.

The plastic sheeting is attached to the door card.

I suppose the logic behind it was that it makes access to the door cavity very easy and to be honest, assuming that you will use a cavity wax type product in the door cavity to prevent rust, the only part of the door assembly that is vulnerable to water is the door card itself with it being made of..........well, card.
Having said that, the door cards look like they have been painted with some black protective paint.

Best option, fit new door glass seals.

Can I just add that if you "seal" the door with the Dynaplate that you mention, you may end up trapping moisture in the door and turning it into a rust incubation tank.

sheet was moved...

as we know all too well...

But, specifically on my pics, you can see the tape was moved or slid from original location at least once. Wouldn't surprise if it was originally on the door card itself.

The door drains at bottom will not be touched, and all seals will be replaced, but at least some atmosphere will be able to enter through top and bottom. Still, you're probably correct about fully sealing the door. I do believe that stiffening the panel is a benefit no matter what.

Cavity wax... thank you! This is something I probably should think about putting in the bottom and heat gun the area... But, that kind of stuff (cosmoline, etc) can get everywhere. Bit afraid of that... Most areas on rest of car were hit with epoxy primer. Hmmm... choices...

My Mk1 was a completely unmolested tiger. It had felt attached to the door skin and the door cards. No plastic. My alpine 5 was the same, it had felt glued to the door skins and the door cards. Slightly off topic with the door cards, use the ply attached to plain house doors it is very good as a replacement.

I have restored many Mustangs and the have the barrier similar to that on the doors too, but more like butcher paper--water barrier I have been told. I unfortunately have not seen it on a Tiger.

Maybe I was not clear, the felt was glued to the inner part of the door skin. Then the door card was attached. Make that a bit clearer?
