Scotch Brite Hand Pad Comparison

I use Scotch Brite abrasives to put a brushed finish on some of the jewelry I make.
Recently I decided to be a bit more scientific, and bought 4 types, with different degrees of fineness.

A copper sheet was used for the test. Sterling would have been better, but I can't afford to sacrifice that much to science.

6444 Medium

7447 Very Fine

7448 Ultra Fine

7445 Super Fine

I use the 7448 Ultra Fine for most work, and the 7447 Very Fine for some basic scratch removal beforehand, should the work need it. I don't see a big difference between the 7447 and the 6444 Medium in terms of scratch pattern. I have used the 7445 Ultra Fine before polishing to good effect once or twice. Anyway, I mostly documented this so I could remember which pad is which, as the Very Fine and Medium pads look a lot alike (one is maroon, the other brown), and there are no intelligible markings on the pads themselves.

You can even use them to clean your pots and pans!

Here is the color of each pad in order from coarse to fine:
6444 Brown Medium
7447 Maroon Very Fine
7448 Light Grey Ultra Fine
7445 White Super Fine

How do you use the 7445 White Super fine (i.e. how are you actually doing the polishing - just rubbing?)
I've tried using 7445 on 6061 aluminum and it doesn't seem to make a dent (whereas 7447 does a great job, but isn't quite as "fine" as I would like)

Yes, just rubbing. Depending on how much surface area you are applying pressure on, you get different scratch patterns (heavy/light). I found that first using a coarser pad (7447) and then using the white (just as with sandpaper) helps get a finish, alone (unless on a polished surface) the white won't remove any heavier scratches.
