Accumulator, for polishing I use Optimum, Menzerna, 1Z and Riwax products. I haven't tried FK1 polishes yet. However, their AIO-like products are excellent, and for protection I cannot imagine anything better.
Mike, here is my process. First, I secured the discs with a double-sided tape to a piece of plexiglass. After two or three attempts, I faced with difficulties, because some of the discs are sensitive to the tape. (It can remove the print.)
Then I chose a very thin DVD case, cut the edges and the other unnecessary parts and I taped it to the plexiglass. It holds the disc securely and allows it to spin freely under the pad. The disc actually turns slowly counterclockwise and the DA does the rest of the job. I run it between 4.5 to 6, depending on the condition of the disc. I use a white Riwax polishing pad which produces a very fine, usually absolutely marring free finish. I use 0.1-0.2 ml of 1Z HGP per disc. I prime the pad with FK1 #425 and go. It takes 10-20 seconds to finish an average disc. Depending on the damage, I sometimes apply pressure, but usually not much.
When the damage is very heavy, I use an even more aggressive product, such as AutoGlym PR, 1Z PI, or recently I tried the Carlack Heavy Scratch Remover paste. Of course, the deeper, fingernail-catching RIDS are totally unremovable but the surroundings will be fine enough to play OK. I remove the product with a suede MF and a spritz of #425.
Here you can see the restoration of a heavier damage:

Damaged disc; skips, freezes, etc.
Amount of AGPR for pad priming/heavier correction
Usual amount of 1Z HGP
During the process (Demo pic: I lifted the pad immediately after starting the DA. As the disc turns counterclockwise, you can observe the spreading/trace of polish on the surface.)
