On polystyrene Mercurys I've noticed grey splotches or entire sides which 
seem related to the ageing process rather than sleeving.  The crunch 
fiercely.  This is true, to a much lesser degree, with a few early Columbias 
until their vinyl improves.  I don't know the cause and these seems no cure.
