2. Specific steps:

(1) Clean the car body with clean water first.

(2) After smoothing the sandpaper with a stow-wood, wipe the scratched edge with water. Grind until the edges are smooth and the transition from the paint surface to the primer is smooth.

(3) Pour the mending soil on the scraper, and evenly spread the mending soil on the scratched surface with the scraper. It should be slightly higher than the paint surface after repair. After patching, wait until the patching soil is completely dry before proceeding to the next step.

(4) After the mending soil is dried, use sandpaper dipped in water to polish the mending soil. Polished until the repair surface is parallel to the paint surface, and it is smooth without edges and corners manually. After cleaning and drying, the next step can be carried out.

(5) Before painting, cover the important parts around the scratches.

(6) After the cover is covered, you can start painting. If it is a plastic part, it is recommended to spray primer first to increase the adhesion of self-painted plastic parts.

(7) When spraying colored paint, attention should be paid to painting techniques. Wait 3-5 minutes for each layer before spraying the next layer. Repeat spraying for many times until scratches and dirt are completely covered, and there is no difference with the color of the surrounding paint surface.

(8) Wait for 20 minutes, and after the paint surface is dry, polish the paint surface with scratch repair agent. After polishing, prepare for the next step.

(9) Spray the joint between the new paint and the original car paint for 2-3 times, so that the transition between the new paint and the original car paint is more natural.

(10) Finally, spray varnish to make the paint look brighter. The varnish needs to be sprayed several times, once every half a minute. After spraying, the whole painting process is completed.
