What exactly is car body and paint painting

Small scratches and scratches on cars are inevitable. People may get injured and go to the hospital, while cars may get injured and go to the 4S dealership (repair shop). When faced with maintenance, many novice drivers are not familiar with many automotive repair terms and techniques. Many times, a repainting job is said to be about making sheet metal, but you don't even understand what sheet metal is. Today, let me talk to you about the sheet metal and paint spraying of auto repair.

Job types for automotive maintenance

Before introducing the repair of car body and paint, Brother Wuyou thinks it is necessary to first popularize the job types of car maintenance. Usually, we can divide the job of car maintenance into three categories: mechanical and electrical (mainly repairing the engine and chassis), sheet metal (mainly disassembling and repairing the appearance of car parts), and paint (mainly for repainting and beauty).

Remembering this division of labor is very helpful for car owners, especially when the car needs to be repaired, they can have a clear idea based on the damage situation.

Which car repairs require sheet metal?

When does sheet metal need to be used when a car is damaged?

a) Uneven vehicle body; b) Severe rusting; c) The frame is twisted and deformed; d) Structural component replacement.

It can be simply remembered that once the appearance of a car is misaligned or deformed, and needs to be reshaped and repaired, sheet metal will definitely be used.

Steps for sheet metal painting

The operation of sheet metal depends on the situation of car repair. Generally, the damaged parts of the sheet metal are dismantled, and the original paint of the damaged parts is polished off in the next step. If there are dents in the sheet metal, tools need to be used to flatten the sheet metal, and then heat treatment is required.

To paint, first polish a transition surface between the damaged area and the paint surface, then apply primer to the damaged area, scrape putty, clean and degrease, and then spray the intermediate primer. After drying, polish it.
