According to the bumper you said, for example, the bumper is plastic, and the sheet metal is generally made of baking lamps and plastic guns, plastics, etc., if it is a large pit, it can be heated directly with a baking lamp to restore to its original state, if it is a relatively large hole, choose the same type of plastic, and repair it with a heating gun.

Then scrape the putty, the first time it is higher, and when it is dry, smooth it with sandpaper, scrape the putty twice, grind it again until it is flat, then spray the primer, and find out the sand hole, repair it with red ash, and grind it flat; Blow off moisture and spray paint.

The first time the paint was sprayed.

Often-said color paint), spray after waiting for more than 10 minutes and then spray, until the primer is covered, and finally wait for a while to spray bright oil (commonly known as varnish), generally spray three times, each time should not be posted, after which it will flow and produce a sag. Try not to spray paint in dusty places, it is easy to adhere to dust.

That's it!

As an auto mechanic, you must be proficient in the auto sheet metal repair process. Because automobile sheet metal maintenance is not only related to the appearance of the vehicle, but also directly related to the safety of the vehicle. Below, we will introduce the relevant knowledge and skills of automobile sheet metal repair in detail.

Automobile sheet metal repair is a high-tech work, which requires maintenance workers to maintain and modify the sheet metal with various tools, and to ensure that the repaired vehicle is guaranteed to be the same as the original vehicle appearance and structure as much as possible. The necessity, process, tools and precautions of automobile sheet metal repair must be mastered, and only by continuous learning and practice can we gradually improve our own maintenance level.

3.Pay attention to safety: When carrying out welding and oxidation work, safety measures must be taken to prevent accidents.

2.Dimensioning: The length, width, height, and geometry of the body parts must be measured prior to repair and dismantling to ensure that the dimensions and appearance of the repaired body are the same as before.

The necessity, process, tools and precautions of automobile sheet metal repair must be mastered, and only by continuous learning and practice can we gradually improve our own maintenance level.

4.Metal Hammer: The squire is used for hammering and adjusting during sheet metal repair.

2.Electric drill: used for drilling holes in sheet metal repair.

1.Mill: used for sheet metal grinding.

1.Bending or protruding of the repaired area: Due to unskilled or unfamiliar knowledge of the properties of the material, the repairer will over-polish the repair, resulting in the bending or protrusion of the repaired area.

Therefore, in the maintenance process, we must pay attention to the strength and avoid excessive polishing.

In the process of automobile sheet metal repair, there are many kinds of tools that need to be used, which are listed as follows:

(1) Sheet metal disassembly. The sheet metal parts of the damaged parts of the collision vehicle are removed from the original body by cutting or other means.

2) Damage confirmation. After the damaged area is cleaned, the extent of the damage is confirmed, and a repair method is established.

3) Remove the old paint film. The original paint on the damaged part is sanded until the iron plate layer is exposed.

4) Sheet metal parts are leveled. According to the degree of damage to the sheet metal parts, the corresponding sheet metal tools are used to flatten the depression parts. After the leveling operation, the surface of the sheet metal parts should be finely adjusted for flatness.

5) Collect the fire. The tensile and extrusive stresses generated by the metal in the process of restoring its original shape and thickness are eliminated through the re-ignition treatment, and the stiffness and strength of the sheet metal parts are maintained.

6) Polishing the feathered edges. A buffered slope is sanded at the connection between the damaged part and the surrounding paint film, so that the newly sprayed paint surface can be better connected with the original paint surface.
