The techniques for applying putty in auto body repair and painting are: fill and level step by step, starting with large dents and gradually correcting the surface. Below are considerations for putty selection: 1. Choose based on vehicle type: Domestic cars mostly use homemade oil-based putty. Mid-range, high-end, or imported vehicles often use two-component body fillers, such as NAPA body filler, fine putty, fiber putty, metal putty, alloy putty, etc. 2. Choose based on the filling layer: Generally divided into filling type, intermediate type, and spray-filling type. Filling type putty is suitable for filling large dents on component surfaces or seams of vehicle body components. This type of putty has high strength, good buildability, and can be applied in thicker coats at once. The moderate spray-filling type putty is suitable for covering scratches, pinholes, and minor unevenness on component surfaces.
