"Water dam paper" ? ( door trim panels)

[Guest DeSoto Frank]

My latest project is conservation of a very nice survivor Rambler convertible.

The shop manual mentions a "water dam paper" barrier between the door structure and the interior door panel.

Does any know what type paper this is and any sources for replacements ?

( the originals have gone missing from my car )

Thanks !

:cool:

Back in the day, this paper may be best described as heavy kraft paper with a light coat of paint on one side. Plastic would work just as well, unless you are a stickler for originality; even though no one can see it.

Some of my early '60s MoPars have the plastic moisture barrier.... would like to go OEM with the Rambler if the materials aren't too exotic.

Would the painted side have faced the door or the trim panel ?

Thanks,

I would imagine that the painted side would face the area where the moisture weeps in the most. I think that it should face the door and not the trim panel. If not, someone please educate me.

I suspect that they used a heavy weight water proof kraft paper. If you painted it, I would use clear laquer instead of paint with a color. The ones that I have seen use paper that is about twice as thick as what is used in brown paper bags.

I can get my hands on some good old kraft paper; I guess I can spray one side with clear polyurethane ?

Thanks for the suggestions !

Painted side faced the door panel. My old ones were painted black and glued in various places around the door panel

We use "rosin paper", a water resistant paper roofing underlayment available at any big box home improvement store. Works well and very inexpensive.
