don't know what grit size rottenstone is but it sure polishes up axles real fine. It's finer than pumice. mostly used to rub out polyurthan or laquer finishes? was doing a google search but couldn't find chart listing rottenstone as compared to 1200 wet/dry paper??

Rottenstone is limestone and is finer than 4F or the finest pumice. I have never used pumice and would not bother.
In getting a master sheen on wood one uses 400, 600, 800, 1200 then 4F pumice followed by rottenstone. I do not have a direct correlation to grit but grit and abrasion is not the same thing. Grit as I understand it speaks to particle size however particles like diamond may be more abrasive than other substances like oxide of the same size and some mediums break-down faster at high speeds or beyond certain levels of pressure...
Generally speaking if it is refined / graded and used properly it is much finer than 1200 grit.
This is one reason to get the right result one must also use the correct speed for polishing as well as the correct level of pressure otherwise the abrasive capabilities can be compromised.
You can crush the abrasive or not allow it to take sufficient material in use. Also the finish depends highly on the solution used (fine oil, distilled water et cetera), speed, pressure and time polishing
For instance Solvol (Solvol AutoSol) can be used to cover several stages as it breaks down during use becoming finer - in a predictable way, giving better results. Where as FlexiGrit you just wash off and always get the same level of abrasion.
So to answer your question it is 'finer' than 1200 grit and finer still than 4F pumice, however all must be used correctly. Not as complicated as it sounds, just read and follow directions.
Hope this helps.
No not a polishing nut, just looked myself for better ways ;D
BTW you can find it at ACE hardware for about $5 bucks. Also look at Zip, Zap, and other Rouge like compounds - jewelers have many resources for this... I should know I am married to one - designing-diva.com. Also look at glass polishing supplies, they have very high grit papers to do everything from glass jewelry to jet fighter canopies.
