- Use 320 or 360 waterproof abrasive paper to polish while spraying water, and wipe off the residue in time.
- Then use 800 or 600 to remove the marks of 320 waterproof abrasive paper, and then use the 2000 to remove the marks of 800 waterproof abrasive paper. The same operation can be deduced by analogy.
- Until there is no abrasive paper mark on the surface of the headlight, wipe off the residue with a towel and polish it with a polishing machine until it is bright.
