Transparency, Poor Coverage
The primer or previous coat is visible through the topcoat.

Cause:
- 
Insufficient amount or film thickness of the color coat. 
- 
Colors are not properly mixed. 
- 
The color has been over-thinned. 
- 
The substrate color was incorrect or uneven. 
Prevention:
- 
Use thinner according to the recommended ratio. 
- 
Mix the color thoroughly. 
- 
Use the appropriate primer. 
- 
Polish or use proper polishing techniques. 
Correction: Apply a sufficient amount of paint until full coverage is achieved, or sand and repaint.
