How to Deal with Overspray When Painting a Car?

Use 2000-grit water sanding for polishing, which yields better results; if you use thinner to wipe it off, it may damage the clear coat and leave the surface dull. You can also promptly (preferably before the paint has fully dried) use xylene or banana oil to scrub it off.
Last time when I was spraying the rear bumper, a gust of wind blew paint onto the side mirror. I quickly wiped it off with a damp cloth dipped in car wash soap, removing most of the paint stains. For the remaining small spots, I bought a car-specific paint remover spray, applied it to a soft cloth, and gently wiped to avoid scratching the mirror surface. Afterwards, I checked the surrounding area to ensure no residue remained. This experience reminded me to always use masking tape and plastic covers thoroughly before painting, especially choosing a sunny and windless day for the job. Don't cut corners by skipping protection—if paint gets where it shouldn't, acting promptly is much easier than fixing it later. Otherwise, once dried, it can damage the metal and corrode the paint. Now I've also learned a little trick: test spray in a hidden area first to confirm technique and wind conditions.
Hey, I messed up a DIY paint job and got overspray on the windows and tires. Panicking, I immediately wiped it with a wet rag and nearly left marks. Later, a friend suggested using a cleaner diluted with water to wash the surfaces quickly, which worked perfectly. He taught me to cover non-painting areas with old newspapers or plastic sheets, with windshield protection being key. Now I know not to paint on windy days and never forget safety glasses and gloves. Learning from mistakes is pretty interesting—next time I'll prepare better. Here's a tip: wait a few minutes after spraying to check for splatters, avoiding frantic cleaning that could smear the car.
