Clouding or Mottling

Mottling usually refers to uneven/streaked colour appearance or poor metallic finishes due to uneven thickness of paint and poor distribution of silver granules, usually due to uneven spray pattern, over thinning, or spraying clear coat before the basecoat has dried.

Common Cause

1. Insufficient mixing of paint

2. Incorrectly thinner or thinner ratios

3. Unsuitable spray viscosity

4. Uneven spray thickness and poor spraying technique

5. Insufficient flash of times

6. Spraying to thick or too wet

7. Application temperature

Repair

Mottling can be repaired by re-applying your base coat with a medium wet coat, ensure your do not apply too heavy as this could result in the metallics grouping together.
