Neither a novice nor an old driver will scrape off the car paint because they are unfamiliar with the new car they just bought. At this time, some car owners, especially novice car owners, will touch up the paint without looking, just like they are afraid to go to the hospital for injections when they have a cold.
Reminder: Actually, it is unscientific. Not all scratches need touch-up.
So, how to tell whether it needs to be repaired after scraping? What kind of treatment is more appropriate?
If it is only a scratch on the paint surface, you can directly touch up the paint locally; If you need sheet metal forming, you'd better remove it, so it's easier to process. If the whole door is painted, it needs to be removed.
1. Do not expose the paint, and polish it in a small area.
Generally speaking, it is best not to expose the primer when there are small scratches. At this time, we will find many small white scratches on the car, and we can feel obvious striped scars with our hands. Because the original car paint is generally very thick, the injured part in the small incision is only the topmost varnish layer. At this time, it only needs simple polishing and the price is the lowest. Generally, the local polishing price in a city like Nanjing is between 5- 100.
2. If the paint layer is damaged, touch-up paint is essential.
If the paint layer is slightly damaged due to friction, then polishing can't solve the problem, and touch-up paint is inevitable. Let's check the vehicle first. If the metal layer has been exposed, we must touch up the paint immediately to prevent the metal from oxidation and rust. If it doesn't hurt the metal, it can be repaired later.
3. Why do you need to remove the door when painting?
Even if it is a small car door, if you want the overall paint to be perfect, you must take the car door apart. This can better handle the details, reduce the shielding of other parts and improve work efficiency. If there is metal deformation in the collision, the best way is to remove the door for sheet metal shaping.
4. Is partial touch-up painting better than whole painting?
As we all know, the paint of the original car is precious, and the electrophoresis of the whole car in the main engine factory and the baking temperature of 180 degrees can not be copied even by the best paint repair shop. Therefore, in the case of small area, partial touch-up paint can really protect precious original paint more than total touch-up paint. However, many people have misunderstandings about partial retouching. There are some common misunderstandings that need to be corrected.
Partial complementary drawing is not cheaper than overall complementary drawing.
Because there is no difference between the process of partial touch-up paint and the whole touch-up paint, the requirements for process and color difference are very strict, so a good partial touch-up paint will not be cheaper than the whole paint, and the advantage is that more original paint can be retained.
Many colors cannot be partially polished.
Because of the color difference, many colors are not suitable for local touch-up paint, and the most common one is pearlescent paint. Because there is a layer of pearl powder sprayed between the primer and the color paint, the color difference of the local touch-up paint will be great.
Summary: In addition to large-scale deep scratches, minor scratches are easy to solve, and it is not recommended to deal with broken points; If you must paint, you should know that the cost of painting repair is not very high. If the car paint is not repaired by auto insurance, then the after-sales repair shop is a good choice.
