I had all kinds of leaks into my trunk... found these 1) leaked around bumper bolts , at several locations 2) cracked convertible gutter 3)around tail lights 4) a small PINHOLE (that I`ve later also seen on several other cars, UNDER the seal in the rear right (pass side) corner, where the metals come together, you dont see it with the seal installed and if glued in , maybe seals it , but in my case didnt) check for pinhole there
