Arcadia screen door gaskets

I'm painting the original screen door frames from my 1955 Sacramento Eichler and noticed that there were/are rubber seal gasakets that run the length along one edge. They are in sad shape (or good shape considering they are almost 50 years old). they appear to be a proprietary extrusion, and I have not found any weatherstripping at my local hardware store that would seem to do the trick. Foam weatherstripping would probably disintegrate in a few months from UV. Has anyone dealt with this? I will check with Arcadia, but thought I'd throw the subject out there before being put on hold and bounced around.

Thanks,

Dane Henas
