Heatsink grease

I think that all of this discussion is referring to the heat conducting
material that is applied between the device and the heatsink itself.  It's
commonly white in color and many electronic supply houses such as Newark
Electronics sells it.  It just makes the heat path to the sink a little more
efficient.  

If it wasn't necessary then why is it used in almost every power transistor
application. Or for that matter remove your HEI module from your GM
distributor and see what's under that!
