Agfa 468 and sticky shed? Might it be usable?

[jmoose]

I'm cleaning out the closet and found a half-dozen or so reels of Agfa PEM468 1/4" stock...still in plastic. Virgin. Never been touched.

Anyone know if it might be usable or is it like old 456, better to toss it since there's a 97.4% chance of gunking up the works...

Thanks.
