If I ever need to do this again, I'll order new vapor barriers (about $35 each) to insure clean bonding surface.

PS: A quick way to check your vapor barrier is to remove the Puddle Light and stick your finger inside. The panel will be wet in that location if the barrier is leaking.
For $35@ probably not a bad idea, do it once, do it right, never do it again. I'm thinking of picking up the BSW stage 1 speaker upgrade kit as well and swap out the stereo speakers at the same time... again, dont want to open up the door again while I have the car (the PO replaced both rear window regulators, hence why I suspect they leak).
