What is the general color of automotive primer?
2 Answers
Automotive primer generally comes in three colors: black, white, and gray, with gray being the most commonly used on vehicles. When scratches reveal the primer, it's important to assess the extent of the damage. If the primer hasn't been scraped off, a simple surface paint repair will suffice. However, if the primer is damaged, immediate maintenance is required. Failure to address this promptly can lead to rust formation on the vehicle's surface. During the use of a vehicle, minor scratches and scrapes are inevitable. More severe scratches often damage the paint and may even expose the primer. If exposed primer is left untreated over time, the metal layer of the vehicle body will be directly exposed to air, significantly increasing the risk of body corrosion.
I've had my car repaired many times, and the automotive primer is usually gray or white. Think about it, before painting a car, you always need to apply a base coat first. That grayish primer mainly ensures the topcoat adheres firmly to the car body and prevents rust. I remember when repairing Ford cars, the primer was always a light gray because its neutral color easily covers different body colors. For black cars, manufacturers might use black primer to save some paint, but in most cases, gray is more convenient and practical. Occasionally, if you see the primer turning yellow or discolored, it indicates poor-quality primer or improper storage. Properly applying primer during body maintenance can extend the lifespan of the car paint.
