Or use the same color nail polish to gently smear a layer on the scratch. When it dries quickly, pick up the nail polish remover by hand and evenly smear the repaired nail polish.

First, you can gently grind the rust spots with very fine water sandpaper dipped in water, but don't grind them indiscriminately, but grind them straight in the same direction. After wiping completely, apply a layer of primer. If it is a new scratch, it can be cleaned and directly primed.

How to deal with small scratches on cars?

1, slight scratch:

Small scratches are also called "sun lines". The trick is to apply toothpaste to these small scratches, and then slowly wipe them off, because there are very fine particles in the toothpaste, and slowly wiping them off is equivalent to grinding away the obvious scratches. Generally speaking, the scratches are not very serious, so you can choose to use toothpaste to remove the traces without hurting the deep paint.

2. There are obvious scratches, but the paint is not damaged:

You can use a touch-up pen. The touch-up pen is used to deal with small scars. You need to choose a good color, because the color difference between some touch-up pens and the paint surface is still very large. Although the touch-up pen is very convenient, it also has many shortcomings. For example, it may fall off after being attached for some time.

If the application is uneven, it will also affect the appearance. Nail polish is also a wonderful thing! Because it is actually the same material as car paint, it is also effective for deep scratches, and nail polish can also prevent the paint surface from oxidation and rust.
