That well on the right side has been filling up with water, but only maybe about half an inch or an inch, nothing ridiculous / flooding-esque. The thing is, there's no water above the trunk mat and no leaks whatsoever (I've done a basic water test and placed tissue paper all over the trunk to determine if there was a leak, but all the tissue paper was perfectly dry and yet the well still filled with some water). To me, this means it's coming through the styrofoam from either the side or underneath the car. My current theory is that there might be condensation that's leaking through the styrofoam? Or, there might be water pooled up either underneath the styrofoam or underneath the car? The strangest part about this is that the water only appears when the car is driven... I can dry the compartment out, drive it 2 miles, and it's filled again, but if the car just sits there, it stays empty as far as I can tell. So, I had a few questions...

A) Has anyone seen or heard of this issue before or any ideas what it might be?
B) Any ideas on how to fix it?
C) The outside / top of my gas tank seems to be lined / wrapped in some sort of plastic, possibly mylar... are your tanks like this as well or was it something a previous owner might have done? Could that be causing it?

I also have a SRT-6 if that makes any difference. The issue doesn't seem to be major by any means, it's more a curiosity that I'd like to fix. Thanks for the help, I've been trying to solve this for a couple of weeks now haha.

Thanks guys, I'm setting up to do the repair and had a couple more questions:

A) Are there any more detailed instructions / pictures of how to get the styrofoam blocks out and to dry out the car?
B) Does anyone know the part number for the O rings on the back panel? I was hoping to replace them and do a touch up sealing job, to sort of double the effort.

Thanks for the help guys, hopefully it'll turn out fine and I'll let you know how it goes.

Hey guys, just wanted to give an update. First off, thanks for everything, I wouldn't have found the problem, let alone the solution, without everybody on here. Glad there's a dedicated community to our car. I've uploaded some pictures showing some of our various steps.

My father and I started by taking the interior panel trim off, then the wing plate, and then the spoiler. As you can tell from the attachments, there was a lot of corrosion around a few of the screws and around the spoiler connection. Around the wing plate itself, the gasket was completely ruined and pushed way out of place.

Basically, we replaced the OEM gasket with a EPDM rubber weatherseal. We placed it where we did in the pictures because we wanted a flat-to-flat connection for a better seal... it might result in some water resting just above the Chrysler emblem, on that little shelf, but that water will likely evaporate / trickle out, whereas we felt this would give us better internal protection. We also replaced the O rings on the spoiler and wrapped the spoiler's studs in teflon tape to help seal out water. Lastly, we used some WD-40 spray on the spoiler-to-wing plate connection area to help prevent any further rust. We also, of course, removed the rust from all the parts before reattaching.

We're avoiding taking the styrofoam blocks out, thus far, because we think the water that's already in there can be evaporated out or sucked out through driving and then dried... I'm hoping to avoid it, but we'll remove it if it's necessary. We tried removing the rubber plugs, but there were no signs of water. This fix hasn't been tested yet, but hopefully it's completely waterproof now - we want to remove the water already in the trunk before we perform any waterproofing tests.

What do you guys think?
