Fundamental Rockhound Products: 1 lb Premium Cerium Oxide - Lapidary Rock Polish - Optical Grade

Worked as advertized, happy with the product,

Just pulled my first batch after using this polish and they are beautiful! I let them run 10 days.

I used this to do the final polish on my car's rear glass. It had been seriously scratched when a windstorm blew a trampoline onto it. Of course I had to sand out the scratches in stages (which was several hours work), but this cerium oxide, along with a polisher and felt pad, put the final touches on the glass and the scratch is now gone and the glass shiny new. Nice stuff.

My daughter really loves tumbling rocks even though it take a lot of patience. However, we were not getting that shiny "wet" look that you see in others' finished products. After trying and trying with no success, someone finally directed us here and explained that most of the stage 4 polishing grit found in kits is all terrible. In fact, if it's gray, it's probably not going to do much in terms of shine. But this stuff, we immediately noticed a difference after just a couple of days.

Used in 3lb rotary tumbler after all 4 stages +burnish. The results were amazing! Went from pretty shiny to high gloss wet look luster in a week. Add this to your routine as the final final polish, you won't be disappointed.

the results were okay but I need to use something else. I used this instead of aluminum oxide to polish rocks!

Gave the opals I processed such a perfect glow.

Excellent quality
