2 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.

Product arrived quickly and as described

It is the same as I already have , did not make stones shiny

GOOD STUFF! Much better than What National Geographic Sells.

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

Was nice contributor to my holiday projects and was reasonably priced

We got some rock tumblers around Christmas and they’ve been running since then. We could never get the polished shine we expected, some of these rocks have been final polished or burnished for weeks without getting them to shine. I decided to give this product a try. It arrived four days ago and I immediately started the problem rocks tumbling in it. I just checked today and they already have a beautiful shine when dry! The grit is pricey, but you cut can cut the cost in half by buying five pounds.

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.

Buena calidad y precio, pero no me sirvió pues no me dió buen resultado para lapear metal, debido a que aún cuando su consistencia es muy fina, concluyó que necesito un material más fino para obtener un pulido acabado espejo lo cual no obtuve con este producto.

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.
