Um.  You'd have to keep them separated, too, wouldn't you - the paste would
stick to adjacent boards if you simply stacked them.  So you'd need some
tricksy little spacers, or the fridge would hold hardly any boards.  (I do
hope you weren't considering keeping foodstuffs in the same fridge with a
lead-based product :)
