How long does it take for the smell of sprayed chassis armor to dissipate in the car?

The smell of sprayed chassis armor in the car can dissipate in about two weeks. Here are some methods to eliminate odors in the car: Ventilate by opening windows and doors: First, open the windows and doors to let the circulating air dilute and disperse the toxic gases inside the car. While driving, try to keep the windows open as much as possible to allow the wind to blow away the toxic gases, which also helps quickly remove odors from the new car. Place activated carbon in the car: Activated carbon has numerous capillaries that possess strong adsorption properties. When toxic gases in the air come into contact with activated carbon, they are adsorbed by these capillaries, thereby purifying the air. Install a car air purifier: Car air purifiers work on the principle of active odor removal, breaking down toxic molecules into harmless gases. They can effectively eliminate odors, as well as bacteria and toxic substances in the car.
After spraying the undercoating, the chemical smell inside the car was really pungent, like glue or paint. I left the windows open to ventilate overnight, and the smell was slightly reduced the next day. It's said the odor mainly comes from volatile compounds in the coating, and how fast they evaporate depends on conditions: hot and dry weather with good ventilation might reduce it within a day; cold and humid weather with no ventilation could drag it out to three or four days or even a week. If it's an oil-based product, the smell lasts longer, up to five or six days; water-based or eco-friendly types are slightly better, fading in two or three days. Don't rush to turn on the air recirculation—park the car in an open area and add some activated charcoal bags to absorb the smell faster. Last time I sprayed, I endured it for three days before it was mostly gone, but I recommend leaving a small gap even when parked in a garage. Ventilation is key—once the smell dissipates, the car will feel much better.
