This paper offers a detailed exploration of the history, developments, and future trends in automotive coatings. Initially, cars were painted with varnish that required manual application and multiple layers, taking up to 40 days to complete. With the introduction of spray technology in the 1920s, the coating process became more efficient, reducing time to a week. Further advancements like nitrocellulose lacquers and alkyd enamels improved durability and color options. The 1960s saw the advent of acrylic enamels, providing greater resistance to environmental factors. The paper also discusses modern coating processes, which involve five main steps: pretreatment, electrodeposition for anti-corrosion, application of sealers, primers, and topcoats (basecoat and clearcoat). These advancements improved durability, appearance, and environmental compliance. Innovations like smart coatings with self-healing properties and smart sensors represent the future of automotive coatings. Additionally, techniques such as powder coatings and water-based primers are now more prevalent due to their environmental benefits, signaling a shift toward more sustainable practices in automotive manufacturing. The review concludes by discussing emerging technologies, such as self-stratifying coatings, that promise even greater efficiency and functionality.
