darb Posted April 1, 2025 Share Posted April 1, 2025 What are these membranes for on the rear door panels; my guess is that they are primarily vapour barriers? Quote Link to comment Share on other sites More sharing options...
RDinNHandAZ Posted April 2, 2025 Share Posted April 2, 2025 Yup they are, and the weep holes along the door's bottom edge is where the melted frost and water escapr from. Quote Link to comment Share on other sites More sharing options...
darb Posted April 3, 2025 Author Share Posted April 3, 2025 (edited) Kind of an interesting decision; I wonder if they are to protect something specific like the wiper motors. Edited April 3, 2025 by darb Quote Link to comment Share on other sites More sharing options...
mrtn Posted April 3, 2025 Share Posted April 3, 2025 No, just to protect the panels, which are not waterproof. Quote Link to comment Share on other sites More sharing options...
darb Posted April 4, 2025 Author Share Posted April 4, 2025 Thanks, that makes sense. I am painting both sides of my panels, so I will skip the $38 (CAD) per pair then. Quote Link to comment Share on other sites More sharing options...
Don Ridley Posted April 17, 2025 Share Posted April 17, 2025 You can make your own vapor barriers with thick plastic film and butyl rubber tape/rope used to seal windows. Probably a good idea if you live in a wet, cold environment. Quote Link to comment Share on other sites More sharing options...
