Appears to the naked eye as a loss of gloss, close examination under low magnification reveals a large number of minute cracks.


Excessive stresses in the paint film due to:

  1. Inadequate mixing of materials prior to application, insufficient thinning or the wrong grade of thinner.
  2. Excessive film thickness, colour coat applied over inadequately dry or excessively thick under coats.
  3. Incorrect use of additives.



  1. Always mix paint thoroughly, and use the correct amount of recommended thinner.
  2. Use correct spraying techniques. Apply paint in thin, web films and allow adequate drying time between coats.
  3. Only use approved additives.



Sand the affected area down to a sound, smooth finish and repaint.
