That is finished off nicely!!

I need to do this to both of my TRUE's, I wish that Thermalright would just polish them to begin with...

As I already posted, for normal operation the polishing does absolutely nothing in most cases. One could call it a waste of time. Just lap the bases flat with max. 600-800 grit wet/dry sandpaper and some water and soap. The most important thing is to use a really flat surface to lap on. Flat is much more imortant than shiny.

BUT, the polished finish looks nice. That's why I did it, now that I want to sell the heatsink.

Edit:

The steps that lead to the finish shown above:

1.)

Number one was realizing how bad the base of my TRUE really was.

2.)

It really took some time to get to that. It was perfectly flat, but not shiny at all.

3.)
The final step to get to the finish like in my pic above.
I used good 1000 grit sandpaper and a lot of soap and some water and lapped the base for about 5 minutes. Be careful not to produce new scratches once you've reached a good finish! It should be shiny now, but most likely with some scratches left. At that point, the good old NevrDull came into play. Polished the base with that for ~10 minutes. Then let it dry for a minute and finally polished it using just regular tissues. That's it. Afterwards I cleaned the whole heatsink using dish washing liquid ("Pril Kraftgel"; that stuff really gets the oily polish residues off) and water. Then I dryed it with the hair dryer on full heat and power and let it cool down for some time. At that point it was finally done.
