Overspray happens when liquid paint particles dry in mid-air before landing on a surface. Think of it as a dust storm made of color. It usually comes from spray painting fences, houses, or even other cars nearby.
Your car’s clear coat is tough, so the overspray mostly sits on top rather than bonding deep. That’s why you can often remove it without damaging the original finish. Patience is your best friend here—not harsh chemicals.
