If you are just putting copper on copper then that isn't an issue but most factory heat sinks are aluminum, so to prevent over oxidation they put nickel on them to thwart this potential prob.

I stopped @ 1000 grit because I did not want to round off the edges (even though i used a lap kit, and was careful, it still seemed to be happening on this first attempt of mine)

so because of this, to answer your question, some thin trace of the nickel remained when I was done.
Lokepup01, if some nickel plating is left over then the surface of the IHS is probably not completely flat. If your cooler has a copper base then there shouldn't be a problem with oxidation. A interesting way to see if your IHS is completely flat is to put a few drops of water on the IHS and then place a piece of glass over it. Look to see how the water is spread out ect. This should give you a good idea.

I hope that makes sense

Good luck buddy

Well right now I have been running this system after the lap and new HS for about 80 hours total. My CPU runs at 34c idle and 49C at full load. (prime 95) With a 200mhz X 18.5 multi., (3.7) and the HS listed below, How does that average? If you guys think that isn't good enough then maybe I will break down and go further with the lapp.
I have the 'go big or go home' perspective on this system so I am ready to do what it takes to get every last drop out of it with air cooling, but not if it really doesn't matter.

lokepup01, if you are getting good results now then it may not necessary. In most cases, a completely flat lap does not consist of any nickle plating left over which was sort of my concern. I wanted to make sure you had a perfectly flat surface before you continued.

See attached image of my lapped Opteron 170. Perhaps that will give you a better idea on what it should look like.

Good luck
