I would guess little bubbles as the big ones probably wouldn't fit as well.
I was shopping a local furniture store dumpster for heavy plastic for putting over windows during winter,
and found some industrial strength bubble wrap,
the bubbles were small but I couldn't pop them.
I had to tape a small flap,
where the stock barriers have one,
down by the vent, so water wouldn't flow inside the car.
Just going to say that......
haha bubble wrap. this threads pretty funny to hear what everyone used. i used an old shower curtain
I used the polytarp vapor barrier. should be found in the insulation/ ducting area at home depot/lowes/ watever hardware..

Did my Driver rear door this weekend. It is raining now and still leaks. I should ask on the proper procedure of how to put the shower curtain on the VW as I obviously did it wrong. I double sided taped it to the door card and didn't put anything on the door. Where do you tape a small flap for the water doesn't go into the car?
Taping it to the door card was the problem.
Doesn't seal the water inside the door that way.
On some doors there is an area you can't seal to due to the "vent" at the bottom.
Rain can come down the door and out this vent.
If you don't put an inner flap over it.
The "vent" is it toward the front or back of the door? Or is it just the big hole that the window regulator goes through?
If it exists in your car you'll see it.
Usually near the rear of the door,... on the front doors.
