i would imagie u mean applying it to ur hsf...
anyway, its cake.
just put a very thin layer with a razor blade to spread it.
u will probably need much less than u think if youve never done it before.
whatever u do DONT USE MORE THAN A DOT ABOUT THE SIZE OF A GRAIN OF RICE!
if u need more just add a little at a time.
try not to get any on any resistors or such.
cleanup is best with rubbing alcohol or acetone.
also be sue ur surfaces to be mated are spotless and free of even finger prints.
correct me if im off on this folks as ive only done it once but it came out well
hope this helps!!!
