Whatever glue they used in the olden days was terrible and left stains in the vinyl headliner after a few years. Plus it was generally dingy looking.
So I decided to fix it with SEM Color Coat Mystic White. First you spray on SEM Prep, which is a pretty good vinyl cleaner and conditioner, the Color Coat, then optionally with SEM Tac Free if the final result is slightly sticky. Mine wasn't so I skipped that step.
Unfortunately the recommended Mystic White doesn't actually match the real Porsche colour. So much for Google searches. So I also did the visors.
In this case since I'd be handling them a lot, I did the Tac Free final step.
Came out excellent.
I also installed all the stereo equipment. Since I was replacing the door speakers, the panels had to come off. The window wires were so short just pulling the switch out disconnected them - no chance to take a picture for reference.
Door panel off.
