In car painting, one door counts as one panel. Below are the relevant details: 1. A total of 13 panels: Doors - each door counts as one, plus the engine hood, trunk lid, and roof (1 each), front and rear bumpers (1 each), and the left/right front and rear fenders (4 in total). 2. Primer coating: Before painting, a primer coat must be applied. This better fills micro-pores and sanding marks on the workpiece surface, enhances adhesion for subsequent coats, and reveals any underlying defects. 3. Intermediate coating: This requires preparing a smooth, flawless surface to ensure proper adhesion of subsequent layers and guarantee topcoat quality. 4. Topcoat application: Topcoats are categorized into single-stage and multi-stage paints. Single-stage (solid colors) provide color and protection. Multi-stage paints include metallic (silver) and pearl finishes, applied in layers for superior durability.
