(1) Cleaning and assembly

The repairman must remove the welding slag and adhesive residue, and then clean the body surface. Especially for bare metal surfaces, anti-corrosion materials must be sprayed on them. After the body repair work is completed, it needs to be assembled. The repaired vehicle body, local accessories, parts to be replaced and disassembled parts shall be finally assembled according to the requirements of the original vehicle.

(2) Four wheel alignment

Debug or test run the vehicle. For vehicles with serious collision, be sure to carry out four-wheel alignment. Four wheel alignment is to detect whether the inclination and beam value of each wheel of the vehicle meet the original standards through the four-wheel alignment instrument. If not, it can be adjusted randomly. Only when the positioning data of the vehicle is accurate, the handling performance and stability of the vehicle can reach a good state, and the service life of the tire can be long. Through the four-wheel alignment inspection, if some data are found to be inconsistent with the specified standards, commissioning shall be carried out until all parameters are within the standard range. The supervisor should check the repair quality and then hand over the body for painting.

① The cleaning of the inner ceiling should be careful. The cleaning method is usually to clean a large area with a high-power vacuum tube and brush, and then focus on cleaning the dirt with neutral detergent, and then conduct comprehensive cleaning.

② The specific cleaning method is to use a high-power vacuum cleaner for dust collection, and cooperate with the ceiling soft brush for preliminary cleaning. Then spray the neutral foam cleaner to the top of the suede. The foam cleaner with good quality will hang on top for a long time. After a few minutes, use the special clean soft brush of the ceiling to gently wash, and then use the wet towel to wipe it.

For stubborn stains, it is necessary to spray foam repeatedly, clean up and clean up with another clean cotton cloth along the direction of the top of the roof so as to restore the original appearance.
