Inside door and rear inside water barriers question

[moparfever]

Was the water barriers paper or Mylar that goes between the door panel and door also the back seat panel to quarter panel ? I want to install the original type of material .

It was plastic sheets (not paper or mylar). I do not know the thickness (mils).

Mine had the Mylar “plastic” in between fastened with the weatherstripping type of adhesive. It looked undisturbed when I took the door panels off. It’s a 74 and not sure if it changed from year to year.

That's not mylar. Mylar is a metallic thin sheet of plastic (like the shiny helium balloons). Yours is regular plastic sheets that you can get on rolls. Just find out the thickness used in the original sheets and buy rolls of that thickness. The plastic is translucent. Yes, it is affixed to the inner panels with some type of strip caulk (usually comes in black).

Agreed. Should had left the word Mylar out of the answer.
