How to Polish Car Headlights?

[Nevaeh]

Use 320 or 360 grit wet sandpaper to sand while spraying water, promptly wipe away residues, then use 800 or 600 grit to remove the marks left by the 320 grit sandpaper. Use 2000 grit wet sandpaper to eliminate the marks from the 800 grit sandpaper until the headlight surface is free of sandpaper marks, then wipe away residues with a towel. Coarse sandpaper will inevitably cause secondary scratches while removing scratches and oxidation layers, so finer sandpaper must be used for subsequent polishing.
