I've got some stuff and it works just like when I bought it over 8 years
ago.

I was told by my photoresist supplier that after several years it can
start to flow out the ends of the roll and fuse together. You can simply
trim the roll 5mm or so and its back to normal again. Keep it in the
refrigerator and it should last MUCH longer than the 1 or 2 year shelf
life recommended by manufactures. Companies often set shelf lives on
products just to avoid possible liabilities and increase sales.
