For some mild scratches in daily life，In fact, we don’t need to go to the 4S shop for paint，On the one hand, it will add our additional spending，On the other hand, there are too many paint，It will also affect the quality of the paint surface。Therefore, there are always many ways to deal with mild scratches on the Internet，For example, useful toothpaste、nail polish、and some special repair agents，But are these things really useful?Uncle Brick I will find it for everyone today，Four products with the highest heat to compare。

We will compare paint pens、Car paint scratch repair agent (creamy)、nail polish、Four products of toothpaste to repair the repair effect of car paint，Among them, the first two are relatively professional repair products we buy from the Internet，The latter two are daily necessities that are often exposed to life。

and the scratches on the paint surface，We simulated mild scratches (scratches 1) caused by sharp objects such as keys (scratches)，and similar to the vehicle when the vehicle is scraped to the trees、Step scratch (scratch 2) caused by items such as steps (scratches 2)。and divide these two scratches into 4 parts，Use these 4 products to process it separately，seabet myCompared with that product can handle scratches more effectively。and after testing，Use the most effective product on the real car，To observe its handling effect on actual scratches。So we gossip less，Let's take a look at the test process and results。

Test results

When dealing with scratches，First apply the transparent nail polish to the scratch，Then set up a period of time。

It is not difficult to see from the effect before and after processing，Since we choose a transparent nail polish，Therefore, nail polish only fills the dentan of the paint surface only to a certain extent，and form a transparent coating on the surface，It plays a role in refracting light，Therefore, we reduce the recognition of scratches from some specific angles，But it does not play a real repair function。

The same method of operating with nail polish，But before use，We need to shake the paint pen first。

It is very similar to the treatment of scratches on nail polish，Painting pen is also the same as the simple filling and covering effect of scratches，But what you need to note is，When choosing a paint pen, be sure to choose the same color as the car paint。For example, the paint pen we use in the experiment，There is a certain color difference with the color of the panel，Therefore, it will also cause the effect after repairing is not ideal。

According to the requirements of the product description，To squeeze the scratch repair agent first，Then apply repeatedly at the scratch for 3 to 5 minutes，After cleaning the surface, just clean the surface。

Different methods of covering scratches with the first two products，The principle of scratch repair agent is similar to the principle of polishing，The paint surface will be polished and fused to a certain extent，to achieve the purpose of repair，So you can see seabet myfrom the result。Compared to the first two products，The scratch repair agent is on the color of the car paint，It is undoubtedly the best，But in the filling of scratches，The role is more general。It can also be inferred，For some scratches that expose too much primer，It is difficult to have obvious repair effects。

Due to the toothpaste and scratch repair agent, they are creamy objects，So the same method also used when cleaning。

I have to say，Toothpaste's repair effect on scratches is indeed very surprising，At the same time, it also exceeds our expectations，You can see the cleaning effect of the paint surface，The effect of toothpaste and scratch repair agent is very close，All can improve the color of the paint surface，But in the filling of scratches，No effect。

At the end of the experiment，We used the scratch repair agent，Repair the real car due to the trunk of the trunk，It can be seen that the effect you can see is still very obvious。

Conclusion

Before talking about the conclusion，Let's briefly understand the structure of the car paint surface。Let's briefly understand the structure of the car paint surface、Color paint layer、Primer、metal/plastic board。And the situation that we can repair ourselves daily，Most of them are losses for the lacquer oil layer and color paint layer，If the primer or the gold is damaged by the primer，It is still recommended to go to a professional store to repair，Therefore, we can get the following conclusions from the above experiments:

1.For mild scratches，Toothpaste and scratch repair agents will have the ideal effect。

2.For scratches that have been exposed,，Paint Pen will have the ideal effect，But when you buy, you must pay attention to the same color as the body。

3.For some deep scratches，These products recommended seabet loginby today are difficult to repair，If you want to restore the flatness of the paint surface，It also needs to use professional paint tools such as putty。
