Finns and the Stormovik

I have read that Luftwaffe pilots were surprised by the ruggedness and armor of
the Ilyushin 2 Stormovik and it took some time for them to understand and
exploit its few weaknesses namely the exposed oil cooler. German ground troops
are supposed to have feared the Stormovik more than any other Soviet plane.

Did the Finns have the same reaction to this aircraft both in the air and on
the ground? Did the Finns learn about the aircraft from the Germans before
they saw it on their front?
