The last time I replaced the thermostat on my 1.9 liter I was alarmed at
the pitting on the inside of the aluminum thermostat housing.  I don't know
how likely it is to perforate but  I have wondered if it would be a good
idea to coat the inside with something to protect it from further
corrosion.  Thanks, Neil, for the link to West System.  I sent them an
email asking if they think their product would be applicable for a cooling
system repair.  I'll let the list know what they say if they respond.
