To remove dried car coating agent, you can consider using mild solvents to soften the hardened coating. For example, you can use industrial alcohol or high-proof liquor, applying it to the hardened area. Once it softens, gently wipe it away. Another method is to use medicated oil or banana oil. Pour it onto the hardened spot, wait for a moment, and then gently wipe it off with a damp cloth.
If possible, you can also use a heat gun to apply heat to the hardened area, softening it before removal. Finally, you can opt for a professional coating remover, ensuring you choose a high-quality product to avoid unnecessary damage to the car's surface.
Regarding spots on the car's paint, in addition to rust stains, other stubborn stains can also be a challenge. For example, if the car body has sticky substances like tree sap, or if spots have formed due to not washing the car for an extended period, it's essential to inspect and treat these areas promptly to prevent further damage to the paint.
Remember, keeping your car's surface clean is key to maintaining the paint's integrity. Especially for acidic stains like bird droppings, immediate cleaning is crucial to prevent irreversible damage. Take good care of your vehicle, and it will continue to shine like new.
