Since the vent is by the tail light, and I'm pouring water on the convertible top, I highly doubt it is that either. It must be the rubber lip or something, that would be the only thing that would make sense. Any idea how much they run for and/or difficulty of install [model numbers?]?
I recently replaced the top motor, which required removal of the top; pretty sure you can't replace the seal as it is bonded to the fabric. When I removed the seal on mine, I noticed that the compound within the seal was dried up and cracking, perhaps you have a similar issue which is allowing water to get in. When I put my top back on, I used some non-curing silicone grease to re-seal the rubber lip.

Maybe try opening the trunk, pour water slowly over the suspected area of the top and see if it drips from within the trunk ceiling (where the seal meets the frame) - you might need to remove the soft top compartment floor to view this.

If it is the seal; you can pull the seal out (without removing the entire top), add some silicone grease, put it back together and hopefully resolve the issue.

ShipKiller has an excellent DIY with pics for the top removal:

To just undo the seal, you will only need steps 1-3 and 5-6 of his DIY (no need to do #4). Also, you may not need step 5, which details removing the soft top compartment floor if you are able to see the leak without removing it, but if you want to identify exactly where the leak is occuring, it may help.
