Answer
For Lexan scratches, wet sand with 1000, 1500, 2000, and 3000, then polish.
Why it happens
Lexan is polycarbonate, so clear-surface repairs need fine wet sanding and polishing.
Recommended grit
Use 1000, 1500, 2000, and 3000 before polishing.
Wet or dry
Wet.
Success check
The Lexan has a uniform fine haze before polishing.
What to do
- Clean the Lexan surface.
- Wet sand with 1000 for light scratches.
- Refine with 1500, 2000, and 3000.
- Polish after sanding.
Avoid: Do not start with coarse grit on clear Lexan.
