  • Question: Do I need a tumbler to use this product?

    Answer: Yes, this product is suitable for use with a tumbler.

    Answer: No, the plastic pellets are not included in this kit but can be purchased separately.
  • Question: How much polish is recommended for a 50lb batch of rocks?

    Answer: 50 Tablespoon
  • Question: Can you use this in vibratory tumbler?

    Answer: I'm not absolutely sure but i think you are suppose to use pellets in a vibrating tumbler and or walnut shells. Vibrating tumblers are dry no liquid in them. But of course, I might be wrong. The best place to find out more answers is 'you-tube'. Just type in 'vibrating tumbler'. Also, vibrating is for polishing metals like ammo casings.
  • Question: What’s the best grit for glasslike finish on rocks?

    Answer: If they have not been tumbled yet you will want to do all 5 steps to polish.
