Just like the wet sanding step, periodically wipe off the surface and inspect it for a uniform sheen. Re-apply the oil and sprinkle a little more pumice over the oil and continue. Once you have achieved a uniform semi- gloss sheen, you are done. At this point, you have probably guessed that there needs to be one more step if you wish to obtain a high gloss finish. Rubbing with Rottenstone.
Rottenstone is also a very finely ground rock.
It is even finer than pumicestone. Using rottenstone will produce the finest mirror-like finish. Rottenstone only is available in one grade and can also be purchased at woodworking and woodfinishing stores. The process is exactly the same as the pumice process, just make sure you do not use the same felt block that you used for rubbing the pumice, if you do, the pumice will mix with the rottenstone and give you an uneven scratch pattern. Once done, again, clean and apply paste wax or liquid polish.
