generally auto stores, in particular paint shops and model shops, even body restoration garages will carry various sheets of abrasives up to very high fine grits.

Thanks! Alright can you tell me why and if i need oil? And when and how to apply it?

you get the wet sandpaper, and use water while you sand. that will lubricate, you dont use oil. i second autozone or a body shop, homedepot doesn't carry really fine paper.

so lemme get this strait.

Start at 400, and work your way up to 1000, 1200, or 1500.
Some people say that 600 gets you pretty much as flat as you're going to get, so you could even just do 400 and 600. Maybe at 800 and 1000, then see if you want to go further.?
And apply water for each grit i use?

Water is pretty much useless at 320 or 400 grit. All water does is reduce the effective grit of your sandpaper, so use it at higher grits for a better finish.

yeah, you use the finer paper to smooth out the scratches left by the rougher paper. 600 will probably get it as flat as you need, but your going to need to smooth it out, hence the mirror finish. yes, you use water on all the grits, use water all the way through.

Actually, I went to ace to get sandpaper for painting, and it went up to a really high grit. It was at least 2000. And I live in san diego too, so ace should be pretty close.

Thanks a bunch, so you think i should just start off with the 600 grit and skip the 400?
Also should i soak the sandpaper in a bowl of water for a few minuets before or just dap it in water?

I used 300>500>800>1500>2000>2500 lapping on a mirror. I used a spray bottle of water to wet the paper a little and act as a lubricant. Once I finished, I used some brasso polish to get rid of hair line scratches, and then cleaned the surface with some arcticlean TIM remover. Once dry, I used a haze of AS5 (You hardley need any. Just rub some an and wipe it off) on both the heatsink surface and CPU IHS. You are then good to go
