How to Determine Whether the Primer or Bare Metal is Exposed?

[VonSophia]

Gently touch the scratch with your finger. If there is a noticeable unevenness, it means the damage has reached the primer. If it's not obvious, polishing and waxing can solve the issue. Below is some extended information about car paint: 1. Composition of Car Paint: Generally, a car's paint surface consists of at least four layers, including multi-layer paint, primer, topcoat, and color coat. 2. Paint Colors: The primer can generally be divided into dipping primer, water-based dipping primer, anodic electrophoretic primer, and cathodic electrophoretic primer. Most passenger cars use cathodic electrophoretic primer, which is usually white or gray in color, depending on the vehicle model. For example, black cars typically use white primer, while white cars use gray primer, mainly to make it easier to identify the primer when the paint is scratched.
