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.
P**!

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.

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.
