So, I need a smudge of heat sink compound under my SSC star, but I don't feel like going to Fry's and buying a whole crapload of the stuff. I have in my garage two potential compounds which I would like to share with you and get your opinions on regarding suitability for use as a heat sink compound. You may vote which you would guess to be the better of the two, or give your reasons why you feel one or both should not be used.
First is Permatex anti-seize lubricant. It is a thin petroleum based grease with a high metal content of what appears to be aluminum powder, or some other such aluminum-colored metal powder.
The second candidate is Permatex ultra disc brake caliper lube. This is a silicone based lubricant with molybdenum added.
Which would be best for a hopeless cheap-ass to use for heat sink compound? What is the base for a dedicated heat sink compound? And please do not say, "Just go out and buy some real heat sink compound!" If I did that, I just wouldn't feel resourceful!
