First off you will need all the same supplies as for the HS guide, but you will also need some kind of protection for the CPUs pins as outlined in my last post, also i'm adding to the list "Brasso", I got recommended this here and I have to say it works very good for removing very fine scratches after you have finished sanding.
First heres the euro test with the stock nickel plating. You'll want to sand this off until you see only copper, I used about 1 A4 sheet of 230 grit to achieve this.
After a while you'll accept that your warrenty is gone for ever
and you'll start to see all that coppery goodness. From this picture you can see how horrible concave this IHS was, as the copper around the edges has already begun to show and the nickel in the middle is still barely touched.
voilá, naked copper
Here it is after 400 grit
after 800 grit
and the finished article... after 15 grit and a rub down with some brasso.
Here's a few more glory shots... was it worth it, hell yes
. It might of almost
been a very expensive copper pocket mirror for the missus but for now its a perfectly flat,shiny thermally efficient Opty 165
