Recommended Process Pathway

1. Coarse cut (this media) – establish a uniform surface and remove burrs.
2. Medium cut – refine the surface with Medium Cut Dark Green 1/4" Plastic Pyramids.
3. Fine cut – smooth to pre-polish with Fine Cut Light Green 1/4" Plastic Pyramids.
4. Optional burnish – brighten with Stainless Steel Mixed Shot, or proceed directly to a dry final polish.

Notes

• Add water to maintain a thin slurry; refresh compound as needed based on load and soil level.
• Check parts periodically—cycle time depends on metal, mass, and machine type.
• Rinse media and parts thoroughly after use to maintain cutting performance and avoid residue buildup.
