Group 1: Painting Process - The standard single-color body spray requires one coat with an 8-layer paint structure, while luxury brands typically use a two-coat process resulting in a 13-layer structure. Li Auto L9 Livis goes further by adding a third coat, making it a semi-finished product that addresses the thickness difference at color junctions [1]. - After the initial two coats, a team of four skilled craftsmen spends 8 hours hand-polishing the entire exterior to eliminate any minor imperfections, particularly at the waistline, before applying a third coat of high-quality clear lacquer [1]. Group 2: Quality and Performance - The three-coat process results in a total of 15 layers of paint, with a thickness of 130-200 micrometers, significantly exceeding the typical 90-120 micrometers of standard paint. This additional thickness provides 2-3 times the protection of conventional clear coats, ensuring the paint remains vibrant over time [2]. - The Li Auto L9 Livis achieves a mirror index of 95+, surpassing the industry standard of 92+, and a surface smoothness rating of 10, compared to the standard 8.
