- Under reduction and/or air pressure too low.
- Thinner/reducer evaporates too fast for spray conditions.
- Excessive film thickness or piling on of heavy wet coats.
- Improper spray gun set-up.
- Improper painting technique.
- Compound or polish to reduce surface texture.
- Or, sand smooth with 1200 or finer grit sandpaper, compound and polish to restore gloss.
- Or, sand smooth and refinish.
- Use proper reduction ratio and spray at recommended air pressure.
- Select recommended thinner/reducer based on temperature, humidity, air movement, and size of repair.
- Avoid heavy coats and excessive film thickness.
- Use recommended spray gun, fluid tip and air cap for the material being sprayed. Always adjust the gun for best atomization and balanced spray pattern before paint application.
- During paint application, hold the gun perpendicular and parallel to the surface. Adjust speed of pass, pattern overlap, and distance from the panel to achieve the desired appearance.
