Did not polish rocks. I ran 2 batches with a different polish and one with this. The other batches turned out great. But the batch using this product as stage 4 never got shiny. Waste of money. Then I switched to polyplastics brand and reran the same stage and they came out great. I believe that MJR had a very large bulk batch mislabeled. What I was sent was not stage 4. It was more likely stage 3.

This was sold as polish. It is not. It is pre polish. It is silicon carbide not aluminum oxide. I used it as a 1500 prepolish, the polish and all I can say is, how big of package can I get!! Took my shiny tumbles to a whole other level!! The results were fantastic!!! I'm now doing a 5 stage tumble instead of 4!
