halfords had up to p800 sandpaper
B&Q only had up to P600

Pay your local auto paint dealer they'll have stuff up to about 2000 grit. The stuff your after is also k.nown as wet 'N' dry

google "CPU lapping kit".

For the rip-off-merchants that they are, halfords will have everything you need.
Failing that, any automotive paint supplier.
Shouldn't cost you more than £2 total for 1 sheet of each neccessary grade.

Halfords do a 4 pack for £2.99 that comes with 2 shhets each of 300, 600, 800 and 1200 should be all you need...

I'd use wet and dry not sand paper

Halfords do a kit from (120-1200 iirc) and a 1500 grit. I just bought these and a sanding block. The rest is simples.

I would be carefull with a sanding block you want something Flat I use a piece of cut glass about A4 size. Remember you are aiming to get the cpu surface as flat as possible the finish is less important.

I turn the sanding block upside down and hold the cpu, i find i have more control
