1. Toothpaste repair method (for minor scratches)
Car paint will scratch unintentionally. In this regard, we can first wash the scratches with water, then rub them gently and repeatedly with a little toothpaste, and then dry them with a wet towel after the scratches disappear or weaken.
It can also play an isolation role and prevent rust. Especially white car paint, the effect is more obvious.
2, nail polish repair method (suitable for minor scratches)
Just like the operation method of toothpaste repair, choose nail polish with the same color as the car paint, apply it evenly on the scratch and wait for the nail polish to dry completely.
Because nail polish liquid can penetrate into the scratches and play a certain role in filling, it can effectively isolate the contact between the iron sheet of the car body and the air and prevent the car body from oxidation and rust.
3, repair method (suitable for small scratches and abrasions)
First, you can gently polish the rust spots with very fine water sandpaper dipped in water, but don't grind them indiscriminately, but grind them 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.
Although this treatment is not as effective as going to a beauty shop, if it is a small or inconspicuous scar, it can also prevent the rust from expanding and aggravating.
What is the cause of car paint foaming?
1. If the original car paint is blistered, it may be that the inside of the car paint is rusted. Generally, after the car paint is damaged, the damaged position will enter water vapor, which will lead to the rust of the metal inside the car paint.
2. If air bubbles appear after vehicle touch-up, it may be caused by poor paint quality, poor touch-up process, environmental pollution during touch-up, uneven paint application and other reasons. The owner can go to the paint repair shop and ask the shop to bear the corresponding responsibility.
