Not that I know of. Note that the tolerance printed on your can was -10% 
+50%.

The need to reform long unused electrolytic capacitors was well known 
everywhere I worked. Nobody ever warned me about any "drying out", and 
mythical electro-chemical effects weren't mentioned either. Back when I 
was a graduate student in chemistry the electrochemists did get a hard 
time,  but back then they didn't have good tools for looking at the 
microscope detail of the very thin layers where the electrochemistry 
took place.

And electrolytic capacitors are even trickier than regular capacitors. 
Charge soak isn't nice.
