The causes of "paint dulling" are primarily:

  • too thick layer of paint
  • too much humidity in the room
  • inadequate hardener/thinner
  • too short evaporation of basecoat / too fast application of clearcoat
  • too fast polishing (before complete evaporation/curing of the paint)

To prevent the occurrence of the "paint dulling"  effect it is necessary:

  • prevent evaporation of painting materials - maintain tightness of cans during storage
  • ensure adequate ventilation of the room
  • do not initiate the polishing process too quickly

To remove this defect, sand the paint surface with fine-grained paper and polish the surface. If necessary, reapply the paint.
