1 LB per Polish Sub Micron Aluminum Oxide 12,000 Extreme Polish Rock Grit Stage 4 | USA

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 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*

Only if 5 lbs but an yes

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.

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.

Excellent for tumbling
