Description

KoolStone's Exclusive 12,000 Grit Sub-Micron Aluminum Oxide Polish stands in a league of its own—significantly finer than typical 800-1500 grit polishes. It removes the microscopic scratches that regular polish leaves behind, delivering a true mirror finish—not just high gloss.

The Final Step for a Higher Gloss Shine: Designed to be used AFTER standard 800–1500 grit polish, KoolStone 12000 grit acts as an ultra-fine finishing compound that enhances clarity, smoothness, and reflective shine beyond regular polishing stages.

Ideal for Final Polishing Step: Perfect for rock tumblers who want more than just "bright shine." This 12000 grit acts as a high-performance finishing agent, bringing out a deep, reflective, glass-like gloss on rocks, gems, and glass—turning shiny stones into display-quality specimens.

Regular polish gets you 90% there, KoolStone 12000 delivers the last 10% that makes all the difference. This ultra-fine powder smooths surfaces at a microscopic level, helping your finished pieces stand out with a clean, mirror-like appearance.

Compatible with Rotary & Vibratory Tumblers: Works with all major rock tumblers and polishing systems. Easy to use for beginners while delivering professional-level final polishing results for experienced tumblers.

Recommended Usage: Add about 2 scoops of polishing powder, then add water just enough to cover the stones. Tumble for 3–5 days, checking periodically and adding water as needed. For larger or harder stones, slightly extend tumbling time or increase to 3 scoops for optimal results.

Best Performance Tips: KoolStone 12000 Grit Polishing Powder performs best in properly maintained tumblers. Suitable for rotary & vibrating rock tumblers, and for best results, ensure your equipment is clean and prepared for the final polishing stage. Beginners are encouraged to familiarize themselves with polishing steps before use.
