OK, heres my trail of finding trunk leaks....first I knew I had a problem as PO had already replaced the trunk pan/... trunk always got wet when washing the car...no need to drive in rain... 1) when I replced the top (its a vert) I found the 'gutter' cracked, replaced it leaks continued 2) heard about tail lights, sealed those up. leaks continued 3) found a leak around right rear bumper bolt...(for this you have to be inside the trunk)...leaks continued 4)I had new rubber seal around trunk opening ,so I didnt supect it....but I pulled it...found a tiny pin hole in the right rear corner where several pieces of metal come together , UNDER the seal ,so you dont see it.....siliconed it....no more leaks.!
