Looking very nice... lotsa progress!

Thinking about the tape on the trunk seams... It probably won't live too long in the environment of the wheelhouses. Invert your idea. Tape the seams inside the trunk (assuming it will be covered by carpet), and squooge a bead of silicone or seam sealer into the gaps/grooves on the wheelhouse side.
Here's something to think about as well.
I had to slightly massage them (heat gun) after the car was Kleinerized, but it didn't take much.
