Before the superbowl i was working on my car a little and my buddy was using my shop to paint the wheels for his teg and work on it a little. My trunk has been leaking for awhile so i had somebody lay in the car with a flashlight and i poured water over everything window, weather strips, tail lights everything. Turns out there is what apperars to be a factory weld on the grove where the trunk closes into. The metal was bent up and it was letting water pour behind the weather strip and behind the carpet. Bent the metal back siliconed it shut and tested it after it dried works fine now posting this up just in case it helps someone else.
