Amazing shine, better than step 4 in kits
Iโm new to rock tumbling and for my first batch used the grits that came with my tumbler. After the full 4 week process I wasnโt 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. Iโve not tried this as step 4 (rather than adding a second polish as step 5) but will do on my next batch.

Great finish ๐ช
Only used on 1 barrel of โbeach rocksโ 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 โstandardโ 4 stages of rock tumbling provides.

Great
This came quite quickly and has polished my tumbled stones up beautifully. It also came with an advice sheet which had some very helpful tips on it. I would use this seller again.

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.

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.
