How much is too much when finishing the axles

I have seen all types of info on axle prep, but didn't see anything on grit to gain ratio. In other words I have found finishing paper that goes up to 12,000 grit, but after 3000 is there any benefit to going on to 4000 6000 8000 and 12000. I am sure there is some even finer than that, but would I be gaining anything to go beyond 3k?
 
Your lubricant of choice has a bearing on this question. I believe you stated in a different post that you have to run graphite? If so, then I wouldn't worry about going over 3-4000 grit. If using oil then I would go all the way to 12k.

If you have to use stock scout axles, take it very, very easy on them. You don't want to reduce the diameter any more than you have to.
 
The 12k grit is micromesh. 3k to 4k is the equivalent grit in "US grit." Both I believe are two micron.
 
I am using some dynasty wheels, and speed axles and some of DD4H's graphite i just wasnt sure if there was any advantage going past 3-4k

I'm not sure about that B? The paper I buy goes from 400 grit to 12,000 grit in the pack. I have Micromesh also but with the sticky cloth back that is up to 12,000 also. Both the 12k's are the same grit.

I went by this chart when I ordered:

I have a very similar chart. I thought the paper you buy in the stores (e.g. an auto parts store) is in ansi, while the micro mesh grit is in those left hand columns.
 
I buy the regular paper from Alpha Abrasives. Appears to use the same grading as the Micromesh?

I have some 3M wetordry paper from the auto paint supply house that looks like it's on the FEPA rating scale, all the grits start with a "P".
 
Something I tried that I like is going all the way from 600 to 12,000 grit, then using a strip of cardboard from the inside of a cereal box or case of Coke, unprinted side of course, and running that dry with Cheetah Kiss polish on it to burnish it before going to the leather strip.

I don't know if it's any "better" but it sure looks nice! The true magic is in the Cheetah Kiss polish though. That stuff is VERY impressive.
