How much is in each grit kit?

The rule of thumb is 1oz of grit per pound of rocks you're going to polish for step 1 and step 2 and 1/2oz per pound for step 3 and step 4.

For example: A 30 pound grit kit doesn't not mean 30 pounds of grit. That would be 30oz of step 1, 30oz of step 2 and 15oz of step 3 and 15oz of step 4.
