KomeStone 5LB Rock Tumbler Grit Step 4 Refill - 1200-Grit Aluminum Oxide Polish, Ideal Follow-Up to Step 3, Compatible with Any Rotary & Vibratory Tumblers, Delivers Final Brilliant Mirror Finish

Features

• Precision 1200-Grit Aluminum Oxide Stage 4 Final Polish for a Brilliant Mirror Finish: Formulated with ultra-fine 1200-grit aluminum oxide particles a polish-grade abrasive finer and smoother-cutting than silicon carbide. Stage 4 removes any remaining micro-scratches from Stage 3 and brings stones to a brilliant, high-gloss mirror finish. Natural color, translucency, and surface detail reach full saturation. Ideal for agates, jasper, quartz, tiger eye, obsidian, petrified wood, and most popular tumbling stones without changing their shape or over-grinding.
• Stage 4 Complete in 57 Days Here's How to Know It's Ready: Run Stage 4 for 5 to 7 days depending on stone type and the quality of your Stage 3 finish. When stones show a mirror-like gloss and colors appear deep and fully saturated both wet and dry they're polished and ready. Stones that appear cloudy or lack full shine may benefit from additional time. Keep the barrel clean and free from earlier grit at this stage to avoid contamination.
• Want Even More Shine? Advanced Finishing Options After Step 4: For a glass-like mirror finish, explore KomeStone's super-polish series 8000-grit Super Polish (Enhances Shine), 12000-grit Polish (Higher Gloss Finish), 17000-grit Super Fine Polish (Extra-Fine Polishing), and Cerium Oxide (Mirror-Like Results). Use any one or combine multiple compounds to achieve your desired level of brilliance.
• 5LB Processes Up to 80 LBS of Rough Stones Use About 1 Oz of Polish per Pound of Rock: At approximately 1 oz of aluminum oxide per pound of stones, one 5LB bottle supports up to 80 pounds of Stage 4 polishing roughly 20 full loads in a standard 4LB rotary tumbler. Adjust amounts based on your stone type and personal preference. Far more value than 1LB single-use options. Store unused polish sealed and dry aluminum oxide stays fully effective between uses.
• Compatible with Rotary and Vibratory Tumblers No Special Setup Required: Works with all standard rotary barrel tumblers including KomeStone K1, K1 Pro, K2, K5, G1, G2, G3, and most popular hobbyist models. Also suitable for vibratory tumblers when used at the correct grit-to-stone ratio. No special preparation or equipment needed simply replace your polish and continue tumbling.
• Step 4 of 4 in the KomeStone Rock Polishing System The Finishing Stage: Stage 1 (60-grit coarse) shapes the stone. Stage 2 (150-grit medium silicon carbide) smooths the surface. Stage 3 (600-grit fine silicon carbide) creates a pre-polish sheen. Stage 4 (1200-grit aluminum oxide) delivers the final brilliant mirror finish. Each stage is designed to work in sequence using all four ensures professional-quality polishing results from rough stone to finished gem.
