I also use Rainex, have been for a couple of years with no problems.  I
have, however had a large problem using Glass Plus window cleaner.  It
caused the gel solution to pull away from the top of the gel, making it
impossible to pour a good gel.  When I switched back to good ole Windex the
problem went away.  The problem may be from siliconizing (rainexing?) both
plates (out of habit from when I was running 0.125 mm gels).  If you notice
this problem, it is probably the Glass Plus not the Rainex.
