The Cheetahs you have are the 23rd generation and are called Cheetah Pucks so they don't get confused with the original pad style Cheetahs. These NEW Cheetah Pucks come in 3" and 5" versions and are 15mm thick. They're HUGE.
The Cheetah Pucks are a 4 step restoration system followed by a quick polishing with an 11,000 grit Monkey Pad if you want to go for a full mechanical polish. If you want to use the Cheetah Pucks with your favorite acidic polishing powder or paste, most marbles can be polished after using step 2.
Here's the grit range of each Cheetah Puck
Can remove lippage on soft stones, replaces 100 metal, 50,100,200,400 resin bond diamond discs. Even though they aggressively remove surface material, even step-1 shows minimal if any visible scratch pattern.
Removes moderate damage and/or preps the surface for powder polishing. Replaces 200,400, 800,1500 resin bond diamond discs.
Removes scratch pattern from step-2 and preps the surface for powder polishing problematic marbles or before step-4 Cheetah Puck for full mechanical polish.
Replaces resin bond diamond discs 800,1800,3500,8000.
Final step in full mechanical restoration before final polishing with 11,000 Monkey Pad. Replaces resin bond diamond discs 1800,3500,5000,8000,10,000 and beyond.
Cheetahs span multiple grits with each step by releasing abrasive material to open and close the pad face. They sense the level of surface wear/damage and start off cutting aggressively but smooth out quickly as the damage is removed.
For people skilled at powder polishing, its an incredibly efficient restoration if you just do Cheetah Puck Step-2 to remove traffic wear and etching then powder polish with a 5x or similar product with an 11,000 Monkey Pad and you're done. USE LESS POWDER POLISH THAN NORMAL OR YOU'LL OVER POLISH AND ORANGE PEEL THE STONE. If this process is done correctly it happens quickly, its easy to over polish. For even better clarity on problematic marbles, follow step-2 with step-3 before powder polishing.
