Body Restoration — General Information (BMW X5 E53)

Carry out body restoration immediately after the defect is detected. The body is most vulnerable to corrosion and operational conditions. According to the degree of damage to the body, corrosion can be divided into three groups - cosmetic, penetrating and structural.

Cosmetic corrosion appears on external surfaces in the form of rust rash in places where the body is connected to overhead parts - decorative trims, lights, as well as on the edges of door flanges, hood, trunk lid. This type of corrosion appears primarily where the paintwork is damaged. Worsening the appearance of the car, cosmetic corrosion, if no measures are taken, progresses and turns into penetrating corrosion. Penetrating corrosion affects the most difficult to visually control places of accumulation of moisture and dirt. It appears when the damage caused by it is difficult to fix. The inner surfaces of box sections, surfaces of the front and rear fenders, thresholds and floor crossbars, the floor itself from the passenger compartment side, internal cavities of the doors are most susceptible to its impact.

Structural (through) corrosion affects the attachment points of the chassis power unit to the body, elements that form the supporting frame of the body. Particularly susceptible to structural corrosion are elements that experience abrasive-corrosive effects - the bottom, thresholds, wheel arches, front and rear fenders. Loss of mechanical strength of these elements leads to failure of the entire car body.
