Been troubleshooting a leak in the trunk of an 2007 Subaru Impreza. Using a hose, found drips at several places around the seal, typically at seams that were not sealed properly (possibly after a rear end collision repair). Sealed 4 such leaks; and still some leakage. So removed the entire weather seal around the trunk, and with a big tube of adhesive coated all the metal and glued the entire seal back on. No leaks from under the seal, but notice a small amount of water collecting on the inner side of the seal/metal interface (on the trunk inside of the seal) all along the lower back edge. In desperation, at night took a bright LED flashlight and shinned it all along the seal from the outside, while someone else opened the rear seat hatch and watch from inside the trunk. Low and behold a small sliver of light was shining thru, at the top of the lower aft portion of the seal, about 1 inch long, right above where the water was found. Opened and closed the trunk again, and did the light check again, and the position of the light shining thru moved and changed length, but still in the general area. So conclusion is that the weather seal is just not seating tightly on the trunk lid, along the back lower portion, which allows water to seep through. I was wondering if anyone knows if the trunk lid is adjustable in order to "pull" the trunk lid tighter down onto the seal? Maybe at the latch? As a final option does anyone know if replacing the weather seal would fix this problem, until it ages and compresses again in the future?
