So...i dont know if im missing some parts or what but...my tunk area is totally vulnerable to water getting into the trunk area! I took the car to a wand wash...and the bloody trunk was covered in soap and water...(Yes the trunk was closed all the way) I have my trunk weatherproofing...why is water getting in!? also there is a gap on each side of the deck lid of equal width on each side between the decklid and the decklid vents where i can see the engine...water and stuff can get in there too! Isnt there supposed to be more protection than that???
It is most likely one of two things. As mentioned above, around the bolts for the spoiler. However that would drip, and probably not have as much soapy water that you are talking about. Run water on the trunk, and see if it is coming through the bolt holes. If it is a fastback, there are "D" trays on both sides of the trunk that are made to capture water, and run it away from, instead of into the trunk. The notchies probably have them as well, I am just not certain. Anyhow, these D trays are 30 year old plastic and quite prone to cracking and breaking. This would let water freely run into the trunk on one or both sides.

Good luck ! I used 3M window weld on my spoiler screws (applied it to the inside) and my trunk has been dry ever since. I did buy a good used notchback trunk weatherstrip but I haven't installed it yet, but the trunk is dry now.

Search for rust and frame rails online and in the real world. These cars are plastic bodies attached to mild steel space frames. You likely need to remove the trunk carpet and wheel well liners at least. Underneath you will probably find extensive rust. It may or may not be practical to patch or replace all of the structure that's missing.
In your search for "frame rails" and in many build threads you will see some really rusted cars that were still driving, but soggy trunks are only a symptom. Aside from your personal safety in the event of an accident a minor bump could mangle what's left underneath, greatly complicating repairs.
Ideally you should weld in patches or even replace the frame rails, but my trunk has stayed nice and dry all through this past awful winter. I don't even weld. It did take a lot of time, paint, and various pieces of aluminium, etc.
No my car has no rust on it, i bought an 88 from from the states (the desert) It was 100% rust free. Super nice. then i painted the frame, coated the frame rails (inside with that rust preventing wax) That was the first time i got water into the trunk. She will be fine, but thanks for the heads up all the same. Really appreciate you guys.
