Flatness is the most important. The mirror finish is just for fun.

Great then, that means I don't have to go to Canadian Tire today to buy some metal polish that was used in your guide.

Nope.

(It was actually car polish, BTW)

Plus, it will usually end up pretty shiny when you get to the finer grits of sandpaper.

The most important thing is to use a flat surface and take your time. Especially when lapping the TRUE, to make sure that it slides easily. The water with dish soap helps with that. Also, don't apply too much pressure. Just use the weight of the heatsink.

I thought the TRUE was slightly convex to get a better fit on the concave heatspreader on recent intel cores?

Well, the one I had was more wavy than convex.

[magictorch]

wavy not good- I guess you dont have much choice but to lap it.

and 2000 grit isn't needed too right? I only have 220B, 400B, 600B, and 1500.

2000 isn't technically needed. In fact, quite a few people find that once you hit 800, you stop seeing meaningful improvements. At a certain point, you're sanding more for shinyness than anything.

I just finished sanding my ultra 120, but I can't make it all copper like. There are still two silver spots, though when I use a razorblade, it shows as all flat, so this should mean its fine right?

No worries - you want flatness. If it's passes the razorblade test, you're fine.
