I can confirm that the diluted airbrushed coating does UV cure when wet
and covered with the usual cellophane - although I only did a brief
exposure to check so I could clean it off again, I didn't do a long
exposure yet so don't know if the other properties of hardness, non
conductivity, soldering heat resistance etc remain.
So that I guess leaves two possibles for the non-exposure of the "dried"
one. Heat damaging the UV cure properties. Or the "drying" meaning
that the oxygen removal of the cellophane layer is not possible (due to
not sticking to it as it does when wet) - as we know, this stuff doesn't
normally UV cure in the presence of oxygen, at least when wet.
Hmm. I don't have an oven that can accurately hold 100 degrees C :-/
