Greg,
I have used another method that is a bit messy, but non-destructive.  I have
used this for checking actual temp of components during operation, but I
would think it would work for profiling also.  Use some method to
strain-relieve the thermocouple wire, placing the actual thermocouple
junction on top of the area of interest, then use a dollop <sp?> of thermal
compound to fill any gap between the area of interest and the thermocouple
junction.  This is a bit messy, but it does clean up with no detriment.  It
also keeps airflow from affecting the measurement, and gives a good thermal
connection to the area of interest.  Just one more method to add to your
list.
