Answer
For aluminum wheel polishing, use 600, 800, 1000, 1500, 2000, and 3000 before polish.
Why it happens
Polished aluminum needs gradual scratch refinement before metal polish can create shine.
Recommended grit
Use 600, 800, 1000, 1500, 2000, and 3000 before polishing.
Wet or dry
Wet for finer stages.
Success check
The aluminum has an even fine finish before polishing.
What to do
- Clean the aluminum wheel thoroughly.
- Start with 600 only if scratches need removal.
- Refine through 800, 1000, 1500, 2000, and 3000.
- Polish after sanding.
Avoid: Do not polish over visible 600-grit scratches.
