Cleaning, identification, assessment and shielding: after cleaning the entire vehicle, identifying the type of old coating, assessing the extent of damage to the work, and determining the process of repairing it; 2. Sheltering, de-oiling: protection of the area around the damage, with covering paper, and de-oiling of the area requiring grinding; 3. Removal of old paint, grinding of the feathers: selection of the appropriate type of sandpaper and grinding machine to remove the old paint from the damaged area and to remove the feathers; 4. Scratching: cleaning of the work, after cleaning of the oil, picking the appropriate amount of polish, and roasting it with a red-line light; 5. Grinding and coating: grinding with a grinding machine or hand-grafted piece of sand paper in a manner appropriate to smooth it, and if need to be scraped in a timely manner, avoiding the subsequent period of work due to problems. The old coatings around the grubs should be smoothed with sandpapers; 6. Cleaning, oil removal, covering: after the work has been finished, the dust of the surface of the windguns should be blown out of the surface, the area around the grub will be wiped out with the oil removal agent, and will eventually need to be covered by the underpainting area in the spray; 7. Painting in the spray: if the parts of the work containing the exposed metal should be made rustproof, then the two- or three-skinned medium paints should be sprayed and then dried; 8. Painting, mid-floor polishing: after full drying, coating or spraying, and then smoothing with a suitable type of sandpaper and grinding machine. After grinding, check in time, and if there are any defects such as needle holes, scratch marks, then smooth the area of the transition by filling it with a glitch or double-assembled grub; 9. Based on the damage to the plate, we have chosen the repair process of plate patching (inter-plate transition) so that, in addition to grinding the wings, the adjacent doors should also be polished. So, when the mid-scrap is finished, other parts of the wingboard and the front door are humid with a canteen, which is applied evenly until the ointment is applied in conjunction with the barber; 10. Cleaning: after the grinding has been completed and the examination is complete, the wingboard surface is cleaned and dryed with water; 11. Garment, oil removal: the work around the wingboard and the front door is properly covered with shrouded paper and tape. Once again, the wings were completely cleaned out. The middle varnish is essentially the same as the varnishing and spraying methods. Depending on the characteristics of the different products and the requirements for their coating。
