Lapping Zalman Waterblock

[redbull555i]

I'm trying to lap a Zalman WB3 Gold Waterblock. The problem is it's covered with a thin gold plate. I'm not sure how thick the gold coating is... or if it's even worth doing this. Anyone have suggestions about how I would go about doing this?

The plating is generally about 300-500 nm thick...

or about 1/1000th of a mm... I wouldn't do it.

why would u lap one of the best lapped blocks ???

I might lap the gold off... Because gold's worse than copper for heat transfer.

Yea... I'm not too convinced by lapping. I look at one of the best air coolers (tuniq tower 120) and the base looks kind of coarse:

Unless your base is concaved or something I wouldn't lap it, but that's just me.
