what are the 4 polishing products supplied? for how much operation? can you polish soft stone with it ? if not, what additional items to take?

The kit includes 100/120 silicon carbide (rough grind), 700F silicon carbide (fine grind), Iolox 50 (pre-polish) and Raybrite TL(polish). This should work fine in soft stones, just watch them closely as a vibratory tumbler does work quicker than a rotary. This kit will keep you going for quite awhile but if you wanted an extra to be sure, the part number for that is 9-1056.
