Marine Blue

When I replaced my rear seal I used Permatex seal glue which you can buy at any auto store. I removed my original seal and what I found was the same yellow residue that tells me Porsche also originally used something similar to Permatex. I don’t recall seeing any clue at the connection point between the lower door seal and the upper rear hoop seal but IIRC there is a section that inserts into the door seal to keep them together.
