Does Pouring Boiling Water Affect Car Paint?

[VonAsher]

Pouring boiling water on car paint will not have an effect. It does not affect the outermost clear coat layer of the car's paint film. Introduction to Car Paint Process: Car paint primarily consists of 4 layers. The first is the electrocoat, whose main function is rust prevention. The second is the primer, which provides UV resistance, stone chip resistance, and serves as a base for the color coat. The third is the color coat layer, primarily for aesthetics. The fourth is the clear coat layer, which gives the car body a glossy finish and provides stone chip resistance. Introduction to Car Paint Composition: Different paints have varying heat resistance limits. Car paint is epoxy-based and generally consists of four basic components: film-forming substances (resins), pigments (including extender pigments), solvents, and additives. Its heat resistance is up to 120°C in air and 80°C in hot water. Original factory paint is baked at 200°C after application. Touch-up paint uses specialized repair paint, which is baked at a lower temperature of only 70–80°C. Therefore, boiling water has minimal impact on original factory paint, but prolonged soaking in boiling water should be avoided. It has a significant impact on repair paint.
