Moving from Atlanta to Portland over the next week. Good to note for potential future issues.Before I reassembled the interior for the "last" time, I went through a car wash test. First up was a pressure rinse. I hit the shark fin with the pressure washer from all angles, multiple times. Through the second row, I felt the floor of the way back and it was wet. I told myself: "it's not too bad, just don't pressure wash the shark fin". I then went across the street to the carnival fun house where sumo wrestlers beat your vehicle with wet rags, or so it seems. More water on the floor. I opened the rear door and felt the top of the headliner...it was dry. I removed the shop towel I placed on the headliner under the shark fin...it too was dry. I looked at the rear door and the interior of the door was wet at the top, as was the door seal. I had two leaks. I'm confident I fixed the shark fin, now I just need to replace the door seal.
Living in a place where it rains a lot and vehicles get covered in pollen and conifer needles, this was something that needed to be addressed. I'm feeling a lot better about it. Maybe one day I'll have a garage that actually fits a vehicle.
