Ouch. Well I bought the above linked paper which they claimed was cold stored. It's in my freezer now. Maybe I will try it out this weekend.
I've had no problem with it in years past using the same safelight I use for RA4, an Osram Duka 50. I use it ONLY for color (which means I haven't used it for years) to save the precious irreplaceable lamp. I now also have a Jobo Maxilux which is supposed to be safe for color. I know the Duka is safe for Panalure. I will test the paper before trying the Jobo.
You're absolutely right of course that regular black and white safelights will utterly fog Panalure which needs to be handled like color paper when it cones to safelights.
