trunk seal

See it this helps. I'm not sure what vehicle you have. This is from my 70 Dart. I've included a photo of the trunk seal end with notes. The second photo shows it going around the lower corner near the bumper. You can see from looking from the quarter panel view where that "top of the V" lip compresses down so it looks like a double lip all around the outer edge.

What everyone else said is good information when installing these. It's not difficult but you do want to take your time and be clean as you work with the adhesive. I agree the 3M black is the way to go. Follow the instructions on the tube.
