2. Mechanical Polishing:

   • Compound Selection:
     • Initial cut: Menzerna PowerGloss
     • Final shine: Autosol Metal Polish

Step 3: Protective Finishing

• Museum-Quality: Incralac spray (2 thin coats)
• High-Traffic: Ceramic nano-coating

🚪 Special Tools:

• Micro torch for spot annealing
• Jeweler's rouge impregnated felt wheels
