Putty is needed after polishing.
After scraping the putty, it needs to be polished before painting.
The paint surface of an automobile consists of four layers, which are electrophoretic layer, intermediate coating, color paint layer and varnish layer from the inside out.
After the whole body is assembled, the robot will soak the whole body in the electric swimming pool, so that an electrophoretic layer will be formed on the surface of the body.
Then, the robot will spray an intermediate coating on the surface of the car body.
The electrophoretic layer is used for rust prevention, and the intermediate coating is also used for rust prevention, which can improve the adhesion with the next layer of paint.
After spraying the middle coat, you can spray the color paint layer.
The main function of paint layer is aesthetics.
After spraying the paint layer, you can spray the varnish layer
The varnish layer can protect the paint layer and improve the gloss of the paint surface of the car body.
Most small scratches will remain on the varnish layer and can be removed by polishing.
However, it is not recommended for riders to polish frequently, which will reduce the thickness of the varnish layer and the paint will lose its luster after a long time.
If you go to an unprofessional car beauty shop, the paint layer may be damaged during polishing.
Be sure to go to a professional organization or a 4s shop for painting.
