4 Pounds of MJR Tumblers Premium Quality Extreme Polish 12,000 Grit Sub Micron Aluminum Oxide Rock Polishing Powder. for Unparalleled Quality and Performance. A Disabled and Veteran Owned Company!

The best polish. Don't trust the kits on here, you need 8000 and above in final stage to get a good polish. This works really well. Always burnish afterwards to complete the stones.

This is the extra fine grit you need for stage 4 or even stage 5 to provide extra polish to your tumbled media. It provide a great shine.

Perfect

I got a Lortone dual tumbler for Christmas and a kit of grit to go with it. I wasn’t getting the shine I wanted with the level 4 grit that came with the kit so I looked at reviews for a final stage grit and this one came up. I am not disappointed! This did the trick! I don’t want super shiny, just a shine but this grit can do both, all about the timing. Excellent product, totally recommend!

Some mild yellow discoloration, but quality seems to still be there. Tons of abrasive for the price, and it works great as a suspension. No clumping or galling from it not dispersing in use. Particle size does appear to be correct for the 14000 grit I purchased.

Be patient tumble a long time and you will be amazed how shiny your rocks will be. Just remember that the finished piece is no better than the base underneath the final finish. Like a paint job on your car, if there are rough patches they’ll still be there at the end.

This polish made my rocks SUPER GLOSSY! Definitely recommend and I will be purchasing again.

Product arrived quickly and as described

Great product great delivery, 100* / 100*

I’m new to rock tumbling and for my first batch used the grits that came with my tumbler. 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.

Only if 5 lbs but an yes

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.

A GREAT PRODUCT WHICH DOES WHAT IT SAYS IT WILL DO. 100*/100*
