Why Don't Toyota Cars Rust?
2 Answers
Toyota cars do not rust because they have full-body sheet metal anti-rust coating. Here are the relevant content introductions: Characteristics of anti-rust coating: The most significant feature of anti-rust paint is its ability to prevent metal from rusting caused by corrosive media to a certain extent. Anti-rust function of anti-rust paint: Anti-rust paint mainly achieves rust prevention through the physical and chemical anti-rust effects of anti-rust pigments. Although anti-rust paint has certain rust prevention capabilities, the decorative quality of the paint film is poor, and it is mostly used as a primer in metal coating. Therefore, applying a topcoat afterward would yield better results.
I've been driving for over twenty years and always felt that Toyotas are less prone to rust, mainly thanks to their excellent material selection. The body uses galvanized steel sheets, with a layer of zinc on the surface that prevents rust, keeping rainwater from seeping in. The factory processes are also impressive—during electrophoretic coating, the entire frame is immersed in paint, ensuring even the corners are thoroughly covered. There are also design details, like fewer gaps in the chassis, preventing rainwater and mud from accumulating, which helps avoid long-term rust. Even after years of daily driving and parking outdoors, I rarely worry about rust spots, saving me a lot on repairs. No wonder you still see so many old Toyotas on the road. Overall, quality and durability are Toyota’s hallmarks, and this alone makes it worth discussing the importance of rust prevention.
