How Long Does It Take to Complete Sheet Metal and Painting at a 4S Shop?
1 Answers
Sheet metal repair and painting at a 4S shop typically take around 3 hours. Sheet metal painting is divided into two types: paint and powder. Powder coating dries faster, especially when placed in a drying oven, while liquid paint takes longer to dry. Sheet metal painting is an automotive repair technique that involves restoring deformed parts of a car's metal body. For example, if the car's exterior shell is dented, sheet metal work can restore it to its original shape, followed by the application of specialized paint to ensure the repaired metal surface matches the rest of the undamaged areas. Automotive Sheet Metal Painting Process: Determining the Plan: Before starting the sheet metal and painting work, the repair technician assesses the extent of the vehicle's damage to determine the appropriate repair method, as different levels of damage require different solutions. Sheet Metal Shaping: Deformed areas undergo cutting, grinding, stretching, heat shrinking, and oxidation treatment. It's important to note that sheet metal work not only restores the vehicle's original appearance but also maintains the hardness of the metal material to the greatest extent possible. Filler Application: After sheet metal correction, the technician uses body filler to shape the car's body lines and adjust its smoothness. Paint Application: The painting process is complex, involving multiple steps such as applying primer, mid-coat primer, color matching, topcoat application, and paint drying. This must be done in a dust-free environment. Paint Finishing: Even after painting, minor imperfections may remain. The technician then uses ultra-fine sandpaper or a polishing machine to refine the surface, restoring the car's gloss.
