After the full 4 week process I wasn’t happy with the shine, so I sought out a better product for a final polish rather than resorting to mineral oil and faking it. The difference this made with 4 days as a second final polish was amazing, even basalt has come up with a shine. I added a spoonful of baking soda to the barrel with this and there was no fizzing/pressure, and rinsing off was easy and quick. I’ve not tried this as step 4 (rather than adding a second polish as step 5) but will do on my next batch. Review: Great finish 🪞 - Only used on 1 barrel of “beach rocks” so far but very impressed with the level of polish it provides, used 80-200-600-1200 grits a week at a time then a final polish with this, Much Much better finish than just the “standard” 4 stages of rock tumbling provides. ## Features - There is No comparison in the results between MJR Tumbler's Exclusive 12,000 grit Sub Micron Extreme Aluminum Oxide Polish and our competitors 1,200 grit or 1,500 grit Aluminum Oxide. 12,000 grit is ten times finer than 1,200 grit with ten times better results! - MJR Tumbler’s Exclusive 12,000 Grit Sub Micron Extreme Aluminum Oxide Polish is the best polish you can buy! - No other polish even comes close to our results. - If you want the best, MJR Tumblers 12,000 Grit Sub Micron Aluminum Oxide Extreme Polish is what you need! - MJR Tumblers is a Disabled and Veteran Owned Company!. ************************************************************* and easy to understand rock polishing instructions with lots of tips and tricks are included with every purchase from MJR Tumblers!.MJR Tumblers is Proud to be an American company located in Pecatonica Illinois in the good ole USA! ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0D4PSKZRH | | Best Sellers Rank | 76,620 in Business, Industry & Science ( See Top 100 in Business, Industry & Science ) 47 in Tumbling Media | | Brand | MJR Tumblers | | Compatible Material | Stainless Steel | | Customer Reviews | 4.7 out of 5 stars 123 Reviews | | Grit Material Type | Aluminium Oxide | | Grit Number | 12000 | | Grit Type | Ultra Fine | | Grit material | Aluminium Oxide | | Grit number | 12000 | | Grit type | Ultra Fine | | Item Weight | 907 g | | Item weight | 907 g | | Manufacturer | MJR Tumblers | | Manufacturer Part Number | MJR-12000-2LB | | Material | Aluminium Oxide | | Number of Items | 2 | | Unit Count | 1.0 count | ## Product Details - **Brand:** MJR Tumblers - **Grit material:** Aluminium Oxide - **Grit type:** Ultra Fine - **Item weight:** 2 Pounds - **Material:** Aluminium Oxide ## Images ![2 LB Polish Sub Micron Aluminum Oxide 12,000 Extreme Polish Rock Grit Stage 4 | USA - Image 1](https://m.media-amazon.com/images/I/61nvojo7R0L.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Amazing shine, better than step 4 in kits *by A***M on 7 November 2025* I’m new to rock tumbling and for my first batch used the grits that came with my tumbler.
