Recommended Process Pathway
-
Coarse cut (this media) – establish a uniform surface and remove burrs.
-
Medium cut – refine the surface with Medium Cut Dark Green 1/4" Plastic Pyramids.
-
Fine cut – smooth to pre-polish with Fine Cut Light Green 1/4" Plastic Pyramids.
-
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.
