Will the original headlights turn yellow after polishing?

[SaraLynn]

No, as long as the corresponding protective agent is applied, the headlights will not change due to polishing. Hazards of polishing: Polishing car headlights will have certain effects because it grinds away the protective layer on the surface of the headlights. Therefore, waxing is usually performed after polishing. However, the wax components on the lamp surface are easily lost. Once lost, without the protective layer, the headlight surface will quickly oxidize again, leading to a decrease in light transmittance. As a result, polishing is needed again. With frequent polishing, the lamp cover will become thinner and thinner, making it prone to cracking. Precautions: Although polishing is effective, it does have certain impacts. If there are minor scratches that do not affect the lighting effect, polishing is unnecessary. If there are many scratches, severe damage, or the surface becomes dark yellow, polishing is not recommended, and replacement is advised.
