Why do cars need to be painted? Will the painting process be very troublesome, and will it take a long time... Do you have any understanding of the issues? Below are the relevant materials that the editor has organized for everyone. Let's take a look together.
Car paint is usually baking paint. After the welding of the car frame and body is completed inside the car manufacturing factory, the next step is painting, generally speaking, the first step is primer. Dip the eggshell into a syrup shaped bathtub and remove the baking primer.
Then it is sent to the cleaning workshop and sprayed with paint using the electrostatic spray painting process. Then dry at around two hundred degrees. To complete more refined processing, you need to apply a layer of varnish. In this way, the process of painting is over.
Its process is not as messy as you imagine, and the following are the relevant processes:
1. Cleaning and judgment
After cleaning the vehicle, identify the type of old coating, evaluate the degree of damage to the workpiece, and confirm the repair process.
2. Covering and degreasing
Cover the damaged area with masking paper and remove any oil stains from the area that needs to be polished.
3. Remove old paint and polish
Select suitable sandpaper and sanding machine to clean the old paint in the damaged area and polish it to the feather like edge.
4. Apply putty
After cleaning the workpiece and removing oil stains, select an appropriate amount of putty to scrape and dry with an infrared lamp.
5. Polish putty and old coating
Use a suitable sandpaper to smooth the putty with a sanding machine or manual sanding block. If it is necessary to apply putty again, it should be applied in a timely manner to prevent rework due to putty issues in the future.
6. Cleaning and degreasing
After polishing the workpiece, use an air gun to blow off the dust on the surface, and use a degreaser to clean the area around the putty, covering up the areas that require primer during spraying.
7. Spraying primer during spraying
If there are exposed metal parts on the workpiece, rust prevention treatment should be carried out first. After the rust prevention primer surface becomes dry, two to three layers of paint should be sprayed on the primer before it becomes dry.
8. Apply indicator layer and apply primer during polishing
After the intermediate layer is dry, apply or spray the indicator layer, and then select a suitable sandpaper and sanding machine to polish the primer.

After polishing and checking that there are no problems, clean the surface with clean water and blow dry.
11. Protection and degreasing
Secure the working components around the mudguard and front door using masking paper and masking tape. Then clean the mudguard and degrease it.
