All of my rocks are beach tumbled. Can I use just stage 3 and 4 to make them shiny. Do I need anything else?

Yes! I’ve done this and these 2 tumbles resulted in smooth and shiny rocks

How many loads can you get out of the 2lb bag typically?

I use 3 tbs of grit per tumbler. You will have to do the math and figure out how many tablespoons per pound then multiply by 2.
