Polishing is to look OK at the time, it won't take long, it will still be yellow, because after throwing, the surface of the original car paint is thin, or even gone, only the original paint and primer are left, less and less bright, especially easy to discolor.
The whole car is painted, it must be better than the polishing effect, and if it is well maintained, it should not change color in a few years, because the whole car is painted, if it is just spray paint, there is not much money, 300-500 yuan is enough, it is similar to truck painting, to spray paint, there is no later processing, the effect is very poor, the surface is dirty and not shiny, even if it is polished, it will not be very bright, if it is paint, then **2000 should be able to take it down, or even cheaper, the whole car will start to bake after spraying, The main thing is to let the paint solidify and dry, and then do mirror treatment in polishing, if you want to be cleaner and brighter, then coat the glaze or something, but I don't think this car is necessary, about**, this depends on what paint is sprayed, and there is the grade of the repair shop, if it is a small repair shop, then**should not be outrageously high, this** is an ordinary paint, if you use a good paint, **will definitely be higher, don't listen to what he said about the original car original paint, it's all, if it's a good repair shop, then** it's not easy to say, I've seen the black Xiali N3, re-painted all the car, after the refurbishment than the original car paint is more high-end, and then I learned that the spray is the black paint of the Accord, which cost more than 2000 yuan, the effect is really good, the money is really not spent in vain, so I think if you want to be high-end, just spray a good paint, if you just want to be clean and neat, then spray the most ordinary, and then polish the mirror, you can.

Automobile sheet metal is a technical means of automobile repair, automobile sheet metal repair, refers to the car body to be repaired after the collision, that is, in addition to the body of anti-corrosion and decoration spraying work.
Automobile sheet metal is a processing method for automobile maintenance, also known as cold work, to say that directly, if the appearance of the body is damaged and deformed, the process of sheet metal is needed.
Automobile collision repair has developed from the original "smashing, pulling and welding repair" to the secondary manufacturing assembly of the body. The repair of the collision accident vehicle is no longer a simple knocking on the sheet metal of the car, and the quality of the repair cannot be observed by the naked eye alone.
Sheet metal operation process:
1) Sheet metal disassembly: The sheet metal parts of the damaged parts of the collision vehicle are removed from the original body by cutting and other methods.
2) Damage confirmation: After cleaning the damaged area, the extent of the damage is confirmed, and a repair method is established.
3) Remove the old paint film: polish the original paint on the damaged part until the iron plate layer is exposed.
4) Sheet metal parts flattening: according to the degree of damage to sheet metal parts, use the corresponding sheet metal tools to flatten the depression parts. The surface of the sheet metal parts should be finely adjusted for flatness.
5) Flame collection treatment: Through the fire collection treatment, the tensile and extrusion stress generated in the process of restoring the original shape and thickness of the metal is eliminated, and the stiffness and strength of the sheet metal parts are maintained.
6) Polishing the feather edge: polish a buffered slope surface at the connection between the damaged part and the surrounding paint film, so that the newly sprayed paint surface and the original paint surface can be better connected together.
7) Apply epoxy primer: clean and degrease the damaged surface after polishing, apply epoxy primer and dry it for anti-rust treatment.
