Pinholes in automotive paint occur due to issues with the oil-water separator. Here are the causes and solutions for pinholes in automotive paint: 1. Problem with the oil-water separator during painting: When there's water accumulation in the spray gun, darker spots will appear on the painted surface. Solution: Remove water from the spray gun. 2. Substandard surface preparation: Inadequate sanding or failure to completely remove dust and sand particles. Solution: Perform meticulous sanding. 3. Poor putty application: Presence of surface bubbles or water spots that cannot be eliminated. Solution: Repainting is required.
