Ok, I look over it and it talks about restoring the playfiled but nothing about general up keep.
You got all that in five minutes?
Its all indexed like a book.
There are a number of ways to machine polish a playfield. One is using the Wen 4" orbital buffer as seen at Topoftheline.com here. This is a good fool-proof 4000 rpm buffer that will prevent burn-throughs. It has an orbital motion and if you press too hard, it will stop spinning, preventing burn-through. Yellow heavy cutting pads are available here, and orange medium cutting pads are available here, and black polishing pads are available here.

Another method is using a drill/arbor based polisher. This will give faster polishing results because a drill system is not orbital, and it is also cheaper. The downside is it's much easier to burn-through the playfield finish if you are not careful. Again TopoftheLine.com sells a 3" drill/arbor system as seen here. Polishing pads in both yellow (for heavy and medium polish) and black (for fine and swirl removing) are available here. Wool pads are available here. TopoftheLine.com also sells a nice 2" drill/arbor buffing kit for around $20 available here. This works nice for polishing between pop bumpers and other tight areas.

The for compounds there are a number of choices. Personally I don't really like the TopoftheLine compounds, but here's a list of what they offer as seen here:
Extreme cut, removes 600 grit sand scratches. Only use in extreme situations. here.
First pass compound heavy cut leveler, removes 1000 grit sand scratches. Levels orange peel really well. Pretty agressive. here.
Second pass medium cut, removes 1500 grit sand scratches. Not as agressive as Heavy cut, still works wells on orange peel. here.
Last pass compound light cut swirl remover, removes 2000 grit sand scratches. This is the last step, and leaves a good shine. here.
Personally I like the 3M brand compounds better, but that's me.

When polishing, if the pad is new or dry, dampen the pad surface by misting it with water. This will aid in compound/polish dispersion. Continue periodic misting throughout the task. I wash the pad in the washing machines after I am done to prevent the compound or polish from drying out or becoming caked on the pad. Do not machine dry foam pads as this will shorten the life of the pad (air-drying is best). Foam pads can become torn or out of balance. This not only shortens the useful life of the pad, but also produces uneven surface patterns requiring additional work. These pads are cheap so don't be afraid to throw a questionable pad out.
I usually start with a medium cut polish and a yellow foam pad. Have separate pads for each polish! That is use one pad for medium, another pad for fine, and another for the swirl remover. I use the yellow foam pad for heavy and medium compounds, and a black foam pad for fine compound and swirl remover. After you wash the pads they can be mixed up, but don't mix used pads. Do not apply too much pressure to the pad. Let it do the work. If you end with a quick and light pass using a dry (no compound) wool pad, this cleans the surface and brings out a nice shine.
What word did you get stuck on?
