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. Below are precautions to take after the automotive primer is scratched: 1. Assess the severity of the damage when primer is exposed in general scratches. If the primer is not scraped off, simple paint surface repair will suffice. If the primer is damaged, immediate maintenance is required. Failure to address it promptly may lead to rust formation on the vehicle surface. 2. During vehicle use, minor or major scratches are inevitable, with severe ones often damaging the paint or even exposing the primer. Neglecting exposed primer over time can result in the metal body of the vehicle being directly exposed to air, significantly increasing the risk of body corrosion.
I remember when I first bought my car and had a scratch repaired at the auto shop, the technician pointed to the newly painted area and said the primer is usually gray. He explained that gray primer is most commonly used because it effectively prevents rust and ensures an even color for the topcoat. I learned that in car manufacturing, the primer is the first layer of paint applied, serving to enhance adhesion and protect the metal parts. In most cases, primer is light gray or gray-white, making it easy to cover without affecting the final appearance. If left exposed for too long, such as from a scratch, oxidation can occur quickly; so I now regularly check the car body to avoid exposure. Gray is mainly chosen for its cost-effectiveness, though some high-end cars may use custom colors, but gray is definitely the industry standard. This principle also applies to other vehicles, like motorcycles or bicycles, where primer is similarly treated—simple and safe.
