What is the paint mixing ratio?

[OTimothy]

Metal paints, such as silver metallic 1K paints, typically have a paint to thinner ratio of 1:1. For solid color 2K paints, the usual ratio is solid color paint to hardener to thinner at 3:1:0.3. If it's clear coat, the typical ratio is clear coat to hardener to thinner at approximately 2:1:0.1. Below are precautions for automotive painting: 1. During vehicle maintenance and repair: Avoid touching the car's paint surface with oily hands or wiping it with greasy cloths. Do not place tools contaminated with oil or cloths containing organic solvents on the car body to prevent chemical reactions. 2. Minimize repainting: If there are no obvious scratches on the paint surface, avoid unnecessary repainting to prevent color mismatch or poor adhesion.
