After a scratch, the painter said he had to dismantle the entire door to repair it. Am I being deceived?

Whether you are a novice or an experienced driver, the new car you just bought will not be scratched or peeled off because of unfamiliarity. At this time, some car owners, especially novice car owners, will not even notice it. Going straight to touch up the paint is like being afraid of going to the hospital for an injection when you catch a cold.

Reminder: In fact, it is very unscientific. Not all scratches need to be repainted.

So, how to tell whether a scratch needs repairing? What kind of processing method is more appropriate?

If it is just a scratch on the paint surface, just touch up the paint locally; if the sheet metal needs to be reshaped, it is best to disassemble it for easier work. If the entire door is painted, it also needs to be disassembled.

1. Do not expose the paint, just polish a small area

Generally, when small scratches occur, it is best to not expose the primer. At this time, we will find many small white scratches on the car, and obvious stripe-like scars can be felt with our hands. Because the original car paint is generally very thick, only the top layer of varnish will be the only area injured in a small scratch. At this time, only simple polishing is required, and the price is the lowest. Generally, the price of local polishing in cities like Nanjing is between 5-100.

2. If the paint layer is damaged, touch-up paint is indispensable

If the scratch is a little more serious and the paint layer is damaged, polishing will not solve the problem. It's inevitable. We first self-check the vehicle. If the metal layer has been exposed, it must be repainted immediately to prevent the metal from oxidizing and rusting. If the metal is not damaged, then it is not a bad idea to wait and repaint it.

3. Why do you need to dismantle the car door for repainting?

Even if it is a small car door, if you want to paint the entire surface perfectly, you need to dismantle the door. This can be done Better handle details, and the second is to reduce the occlusion of other parts and improve work efficiency. If metal deformation occurs in a collision, the best way is to disassemble the door and reshape the sheet metal.

4. Is partial touch-up painting better than full-surface painting?

As we all know, original car paint is precious. The OEM's electrophoresis and 180-degree paint baking temperature cannot be replicated by any good touch-up shop. Therefore, when encountering a small area of ??scratch, partial touch-up paint can indeed protect the precious original paint better than full paint. However, many people have misunderstandings about local touch-up paint. Here are some of the most common misunderstandings to be corrected.

Partial touch-up painting is no cheaper than painting the whole surface

Because the process of local touch-up painting is no different from that of the whole surface, and the requirements for craftsmanship and color difference are very strict, so good partial painting Touch-up paint will not be cheaper than painting the entire surface. The advantage is that more of the original paint can be retained.

Many colors cannot be partially repainted

Due to color difference, local repainting is not suitable for many colors. The most common one is pearl paint. Because the pearl paint has a layer of pearl powder sprayed between the primer and the color paint, the color difference of the local touch-up paint will be very large.

Summary: Except for large-area deep scratches, minor scratches are easy to solve, and it is not recommended to deal with damaged points; if you must repair it with spray paint, you must understand that the cost of car spray repair is not very high. If you don't want to repair your car's paint through auto insurance, aftermarket repair shops are a good choice.
