Trunk leak hunt

I have a 2001 Acura RL with ~170,00 miles on it. I have a persistent trunk leak that I have been unable to track down.
So far I have tried:
Cleaning the drains around the moon roof.
Resealing the roof trim
Resealing the rear window
Replacing the weatherstripping on the trunk

where else could it be coming from? It seems to almost be a "low" leak, in that the trunk lid is dry, but the floor and the molded wells on either side of the trunk are wet--the side pockets even have standing water at times. Any assistance appreciated!

sprinkle talcum powder on the trunk floor after drying all the water then put the hose on it then open and see if the powder shows the track

I have a similar issue. I get drips near my wheel wells and on top of my cd changer. My current theory is that the chrome trim at the bottom of the rear window is letting water through. Would be interested to know if anyone has experience dealing with this trim piece.
