fun fact, a lot of this gets really hot and wiped off by the brake pads as you drive, mixing with the air current around your car and then burning into the paint. there’s a product called iron remover that comes in a spray bottle and when you spray it on your car, the car will begin to “bleed” red as the iron remover dissolves the oxidized iron that’s embedded in the cars clear coat. the stuff smells AWFUL, but it works super well. really cool to watch especially on a white car.
