What are the steps for painting automobile doors?

1. Clean the scratched area with clean water and soft cloth to remove dust and impurities, and then clean the scratched area and its surroundings with detergent.

2. Dip the prepared sandpaper in water and polish the scraped parts.

3. The scraped part is uneven, and it should be smoothed with putty ash, and the recessed part should be filled and smoothed as much as possible, which is convenient for painting and avoids affecting the effect.

4. Stick newspapers and other things around the parts that need to be painted for protection, so as to avoid spraying them to other places when painting. Also, you'd better wear gloves and masks to avoid getting your hands dirty.

5. Do an experiment first and spray it on other iron objects to see if there is any color difference. When painting, the nozzle should not be too close, and it is not required to spray well at one time. It can be done in three or four times, and the paint to be sprayed at intervals is slightly dry, and it can be sprayed once every five or six minutes.

6. After painting, don't worry until the paint is dry. If it is found that the joint between the repaired part and the original part is not satisfactory, it can be carefully polished with fine sandpaper dipped in water to make it look more natural.

7. After everything is done, clean it again and finally wax it.
