Integrated Polishing System Symptoms
- The surface is smoother but remains fully matte after LUXI Black + Sisal.
- No first controlled shine appears before the Calico stage.
Troubleshooting
Hard second-group surface remains matte after LUXI Black + Sisal
A hard second-group surface may need more controlled cut-down until the first stable shine appears, or sanding readiness may need review.
What do material groups mean?
Likely causes
- Cut-down stage stopped too early.
- Sanding readiness is still insufficient.
- Wheel is overloaded or not cutting cleanly.
Checks
- Clean the Sisal buff if overloaded.
- Inspect whether sanding marks remain.
Recommended fixes
- Continue with short controlled LUXI Black + Sisal contacts if the surface is improving.
- Return to sanding if the same defects remain unchanged.
Prevention
- Define the expected matte-to-first-shine transition before moving to the next stage.
