What methods can quickly remove car paint?

[Oliver]

Apply thinner to the paint, wait for it to soak in, then rinse with water to remove the paint. Soak with 10% to 20% ammonia solution or 2% borax solution, then wipe after dissolution.

Having worked in the auto repair industry for many years, I've seen all kinds of paint removal methods, and the fastest is still chemical paint strippers. Choose a product with a good reputation, apply it to the car's surface, wait patiently for five to ten minutes, and the paint layer will soften and bubble up. Then, use a scraper to gently remove it—the whole process takes just over ten minutes. However, this method can be a bit smelly, so make sure to work in a well-ventilated area, wear gloves and goggles to prevent splashes on your skin, and clean up any residue afterward, as it can affect the adhesion of new paint. If you're concerned about chemical exposure, manual sanding is also an option, but you'll need to use an electric sander for even friction, which is more time-consuming. In short, if speed is your priority, chemical strippers are the way to go, but be sure to follow the instructions carefully and don’t rush the process.
