Door vapor barrier install

I just had a glass out paint job done, which required removal of the window frames which I did myself.

While I was in there I decided to upgrade the door speakers. Even though they were the best door speakers on the market in 1977 after years of use they were pretty much spent.

The first thing I did was remove the original vapor barrier and used it as an template.

Kind of hard to make out but it is the old plastic original barrier from the car.

For the new barrier I chose a 2mil thickness drop cloth picked up from your local big box hardware store. Lowes is better they have more metric hardware.

For sealing the barrier to the door I used window ribbon sealer which most auto parts stores have on hand.

I got fancy with my barrier and my speakers, I used the original plastic as my template and then placed the speaker on top where it was positioned in the barrier.

I then used spray adhesive and another piece of plastic to cover the speaker in place.

I then cut the bag of plastic that has now sealed up the speaker.

Bobs your uncle and there you go, a like factory vapor barrier.

Then I used the window sealer to tack the barrier in. I love this material it is sticky as heck but pulls of with no mess.

The window sealer is way too thick for this job it was going to interfere with the door card. I started pulling it off to throw it away and instead of just pulling it off the sealer stretched like silly putty and got much thinner.

I was able to make it as thin as I wanted but it still held the plastic sealed to the door.

The only unfortunate thing was I misplaced some of the screw to put my door cards back on. I usually use the bird for this but I just called my local Porsche dealer and gave them about 10 part numbers and they had all but 2 and they were the self tapping screws that go in the door pocket, Lowes had some that worked just as well. Dave at the Porsche dealer said it was most parts he has ever order that cost less than 100 bucks. My total for the screws was 15 dollars.

I went through this recently with a failed (i.e. rusted out) lower window lift channel on my SC and definitely remember the vapor barrier had another piece to it shaped like a trapezoid that tucked in the long oblong hole in the door between the speaker and the rear of the door.
