anything over 1200 grit is overkill.

it would be a waste. We have seen people on here that get a nice mirror finish using only like 1200-2000 grit. Just gotta do it right. Don't think the 10000-12000 would really make a difference, maybe make it look better, but would be no difference in temps.
But like syrillian said, curiosity is getting to me.

seriously... that is WAY overkill. I'm guessing this is going to be your first time lapping because if you had before you'd of known that 2500 grit (or 10 micron) is good enough. If you use the silicon carbide (SC) sanding paper as well, the grit level on a 2500 grit can eventually get up to over 10,000 grit. Here is the explanation for this from easypckits:

Quote:
SC has a blocky crystalline structure; as it wears, the grains are friable and fracture, exposing new cutting edges. This allows SC paper to have long life and a consistent “cut”.

so your saying that + 4000 grit is bull cause with 2500 you will end up same results as in 4000 + or more....

then why has 10000 been invented ? i don't want to be a smartass but is been used with many reasons for polishing (this also counts for 4000/6000/8000/12000).....

btw polishing sandpaper starts at 4000 and not 2500 maybe to the eye it's polished... and i'm just trying to see what happens... maybe it won't make difference in heat transfer and maybe it does..... at least i can't **** it up and the sendpapers we're only € 0,85 cents a piece
