What are the pros and cons of nano-coating agents for car paint?
3 Answers
Nano-coating agents offer the following benefits for car paint: 1. After coating, the paint is isolated from contact with air, preventing oxidation and avoiding phenomena such as white cars turning yellow or black cars becoming dull within the effective period; 2. The car surface becomes less prone to dust accumulation, making it easier to clean, which is known as the self-cleaning property of the coating. It enhances the glossiness of the paint surface, making the car appear shinier. After coating, especially when using Nissan Amica coating, the hardness of the paint surface increases, effectively preventing or reducing minor scratches. Before applying the coating to a new car, a slow-speed soft paint restoration pad should be used to remove the oxidation layer from the paint surface without the need for polishing, which in itself is a form of protection for the car paint.
I've been using the nano-coating agent for half a year. The benefits are obvious: the car paint has become significantly brighter, looking as good as new. After rain, water beads roll off directly without leaving water stains, saving me several car washes. The UV protection is also great—the paint doesn't turn yellow even after summer sun exposure. The downside is that applying it yourself is labor-intensive; you need to wipe it evenly repeatedly, and the effect lasts at most six months. The advertisement claiming a year is pure exaggeration. A can costs over 300 yuan, enough for three wax applications. I regret not going to a professional shop. It won’t really damage the paint, but for budget-conscious folks, I’d recommend wax—it’s practical and cheaper.
Having handled hundreds of car coating procedures at the detailing shop, I've observed its benefits include isolating bird droppings and tree sap, which can be wiped off effortlessly, as well as protecting against minor scratches. It offers three times stronger UV protection than regular wax, extending the paint's lifespan. However, the application process takes at least three hours, which customers often find too lengthy. Inferior products may leave white spots. DIY attempts can easily result in bubbles, doing more harm than good. I recommend choosing brands with neutral formulations and performing monthly maintenance.
