How to Remove Rust from a Car Door
Rust is not only an eyesore on a car but will grow on the car and eat away at it until there is nothing left. Rust is caused from oxidation when water, salt and road grim collect on exposed metal of the car. Rocks thrown up from the wheels will scratch the paint, leaving the metal exposed. Use touch up paint on these scratches to prevent rust from forming. Remove rust from a car immediately to prevent it from spreading to other parts of the car.
