Tons of abrasive, leaves a great finish
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.

This will get you to shiny!
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!

Extra fine grit
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.

Great 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.

Amazing shine, better than step 4 in kits
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.

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.
