## Questions & Answers

**Q: how much do you use for a 3 lb barrel and how long a run?**
A: We use 4 tablespoons per 3# barrel. We run it 7-10 days. Depending on the results, we may run them again before going to medium grit.

**Q: has anyone used this to make a matte finish on sterling silver?**
A: Have not tried it. I would be afraid it might damage the sterling silver.
