Best stage 4 grit for the $ on Amazon.
Shines up rocks with ease. If your a rock collecting nut that loves to polish rocks like me, this is some of the best prices and available stage 4 polishing compound on Amazon. Batch after batch, I’ve gotten consistent results from Poly Plastics grits.

Pure Aluminum Oxide - Better than other brands
I get an excellent polish with this 1200 grit. Rocks come out way shinier than when using other polish brands. For instance the Rockshed 1000 grit results in dull rocks in comparison. The Rockshed grit color is gray and under a high powered microscope you can see contamination, black particles, which make the overall color of the grit gray. Aluminum oxide, with high purity, should be white.

High Quality
This stuff is a miracle! I tried with 2 other brands. See the top rock and did not get nothing after 2 weeks. The bottom rock was with polly plastics after only 2 days recommend by Agate Ariel from YouTube on how to get a great polish.The only reason I knocked it down a star is because it's expensive compared to others. Definitely will buy again.

This brand works for me
This is the only stage 4 polish I have found that actually puts a shine on my stage 4 rocks. I have tried 3 other brands and have not achieved very good results using them.

Don’t go cheap on stage four!
Poly Plastics saves the Day! I had a pile of failed stage 4 batches collecting from poor quality polish. One week tumbling cycle with your polish turned them all brilliantly glossy. I’m relieved and happy to have found this product.

It works!
I was using a Step 4 product from another company and it just didn't leave my rocks shiny. So I bought this grit to try out. I was very pleased with the results. I use a 3 lb tumbler and added 5 tbsp of this grit at my Step 4 product. After 3 days of tumbling, my quart was shiny. I think after 5 days I would have gotten super shiny rocks but I don't need that with these batches I'm working on now. This was amazing considering that the previous grit I used didn't even give me a hint of shine after 12 days. I will definitely buy again.
