I am using light mayonnaise instead of that expensive Arctic Silver 2 thermal compound. Mayo has excellent thermal conductivity, it's cheap and available locally, and gives off smell-clues when the CPU starts overheating.
To apply it, wipe off any Arctic Silver 2 you may have on your CPU and heatsink, and start applying mayo like you would on a sandwitch. When you have a layer of moderate thickness, place the heatsink on top of the CPU. Lock the heatsink in place and power up your PC.
* Please note that quality of mayo varies and your overclocking results will also varry.
