Yep, know the stuff. It probably isn't in the PET as when the car was being built the assemblers would have just cut this edging trim off of a roll, as they required it. Yes, it does appear in different places, a couple in the engine compartment where the brake pipes and fuel lines go into the strut tower and two pieces on the torsion bar to stop the handbrake cable rubbing on an edge.
Any good automotive trim supplier should have something similar, otherwise go down to the local wrecking yard and pull a load off of a parts car - any kind will do.
Google automotive edging strip...lots of pic's.
The metal inside it does rust and so it can become useless and fall off, so getting some new stuff is a wise idea. It seems to be a PVC rubber composite. Hope that helps.....
