Will spray paint corrode the original car paint?
2 Answers
Spray paint does not corrode the original car paint, but it may cause 'paint lifting,' resulting in irregular patterns. Here is some relevant information about spray paint: 1. Introduction: Spray paint, also known as aerosol paint, typically consists of an aerosol can, aerosol valve, contents (paint), and propellant. It is paint that has been specially treated and pressurized for easy spraying, also referred to as manual spray paint. 2. Uses: Spray paint has a wide range of applications. With recent economic development, its uses have expanded from initially repairing paint flaws to molds, industrial machinery, toys, crafts, musical instruments, buildings, steel structures, advertising and promotional industries, signage, graffiti, and more. It is even used in less industrialized areas like grasslands and pastoral regions, where spray paint colors are reportedly used to distinguish livestock herds among different breeders.
Last time I tried to fix a small scratch on my car with spray paint, it turned out horribly—it actually corroded the original paint, causing bubbles and peeling on the surface. It was so frustrating. Most spray paints contain chemical solvents that are incompatible with the multi-layer design of factory car paint, easily penetrating and damaging the underlying protective layers, accelerating rust. I strongly advise against casually spraying paint; always test a small, inconspicuous area first, and if there’s any adverse reaction, stop immediately. If you want a cost-effective repair, it’s better to go to a professional shop rather than risking ruining the entire panel. Factory paint is meticulously treated, and any DIY attempts may backfire. Corrosion isn’t just unsightly—it also shortens the lifespan of the car body.
