Dull Finish
The surface appears smooth and well-applied, but lacks gloss.

Description: Cause:
- 
The paint viscosity is too low. 
- 
Too much thinner has been added, or a low-quality thinner has been used. 
- 
Poor adhesion of the primer or application of the topcoat over a primer that is not fully dry. 
- 
Application on a poor-quality substrate. 
Prevention:
- 
Use the correct type of primer and allow it to dry properly before applying the topcoat. 
- 
Add the correct amount of thinner according to the product instructions. 
- 
Ensure the paint is thoroughly mixed and applied under proper conditions using appropriate spraying techniques. 
- 
Properly prepare the substrate before painting.
