The Three-Stage Aluminium Polishing Process
Stage 1: Initial Cutting and Scratch Removal
Setup:
- Secure the left or right hand spindle adaptor to your bench grinder
- Mount the sisal polishing wheel and tighten securely
- Start the machine and allow it to reach full speed (2,950 RPM)
Technique:
- Apply Pro-Max brown polishing compound to the spinning sisal wheel for approximately 2 seconds
- Present your aluminium workpiece to the wheel area rotating away from you
- Use medium pressure, moving the piece constantly to avoid linear patterns
- Continue until all scratches and marks are completely removed
- The surface should have a uniform, dull finish when this stage is complete
Pro Tip: Aluminium responds particularly well to proper technique at this stage. Take your time to ensure all imperfections are removed, as this foundation determines your final result quality.
Stage 2: Intermediate Polishing
Wheel Change:
- Stop the machine and replace the sisal wheel with the colour stitch polishing wheel
- Ensure secure mounting before restarting
Polishing Process:
- Apply the appropriate Pro-Max compound (typically blue for aluminium) to the wheel
- Use soft to medium pressure, presenting the workpiece to the wheel
- This stage transforms the dull finish into a semi-bright, uniform surface
- Continue until you achieve consistent semi-bright finish across the entire piece
Stage 3: Final Mirror Finishing
Final Setup:
- Replace the colour stitch wheel with the 'G' loose fold buffing wheel
- Apply Pro-Max blue compound to the wheel
Achieving Mirror Finish:
- Use light to medium pressure for this delicate final stage
- The semi-bright finish will transform into a brilliant, mirror-like surface
- Work systematically across the entire piece
- Apply additional compound as needed, but sparingly
Finishing Touch: Use the provided microfibre cloth to remove any excess compound and reveal the perfect mirror finish.
Professional Tips for Aluminium Polishing Success
Technique Mastery:
- Always polish across scratches rather than along them
- Vary your polishing directions constantly
- Apply compound frequently in small amounts rather than large applications
- Maintain consistent pressure throughout each stage
Common Aluminium Challenges:
- Black grease marks: Indicates too much compound - remove with dry microfibre cloth
- Uneven finish: Usually requires more time with the initial cutting wheel
- Orange peel marks: you will need to sand the area down with wet and dry paper from 400 grit to a minimum 1200grit and then start the polishing process from the start.
Wheel Maintenance:
- Use different wheels for different compounds
- Clean wheels with a wire brush when changing compounds
- Store wheels in a clean, dry environment
Safety Considerations for Bench Grinder Polishing
Essential Safety Practices:
- Always wear complete safety equipment
- Maintain firm grip on workpieces to prevent them being pulled away
- Work in well-ventilated areas
- Never exceed 20-25 minutes continuous operation on your bench grinder
- Ensure all wheels are securely mounted before starting
Proper Workpiece Presentation:
- Always present work to the wheel area rotating away from you
- Keep steady, controlled movements
- Never force the workpiece against the wheel
Protecting Your Polished Aluminium
Once you've achieved that perfect mirror finish:
- Immediate Protection: Remove all polishing residue with a clean microfibre cloth
- Long-term Protection: Apply a quality wax polish to prevent oxidation
- Maintenance: Regular light buffing will maintain the finish
Important: If you plan to anodise or apply other coatings, use a proper degreaser and avoid wax application, as any residue will interfere with coating adhesion.

Troubleshooting Common Issues
Problem: Scratches remain after Stage 1 Solution: Sand down any deep scratches with wet and dry sandpaper until the scratch is removed and then spend more time with the sisal wheel and brown compound
Problem: Uneven brightness in final finish Solution: Ensure complete coverage in Stage 2 before proceeding to final polishing
Problem: Compound buildup on workpiece Solution: Use less compound and clean wheels regularly with wire brush
