Ah! ok, so how much clear coat is left after the sanding and the correction process. I noticed the depth before starting but does that measurement include the colour as well.
Yes, the reading will be total coatings on the metal so will include any paint and clear coat... general rule of thumb is about 30-40 microns of clear coat on a OEM finish.
With Russ' car he started on the passenger wing with this

Wet sanded with 1500 and got this

Then Scholl S3 on a Scholl wool pad = pretty aggressive. To remove the sanding marks

Then refined with 3M polish and pad.

So as you can see... there is a total removal of around 4 microns which is very good for this type of defect removal... as Russ showed in the thread on DetailingWorld, on a softer paint he was able to remove 6-8 microns with a DA machine and the Megs MF system which is pretty scary !
It's obvious from the results gained that this process is about as good as you can get for getting the best possible finish but as Russ also said, its the time that it takes and the skills involved that make it the "extreme" end of detailing. Most people, although they would love the finish, wouldnt be able to justify the cost of having this done over a "normal" correction detail.
Sorry for the hijack Russ... was just looking at the pics from the set and thought i'd help you out
