How to Touch Up Paint on Car With Rust
Before being able to touch up the paint on your car, you will need to remove any rust spots in the area you want to touch up. Car rust can be removed by using a rust neutralizer. Apply the neutralizer, put it on a paintbrush and apply the neutralizer to the spot. Wait a full day and then wipe the neutralizer off the rust spot. Use paint the same color as your vehicle to touch up the spot. If you want a large rust spot removed and an amazing looking touch up, you should take the car to a professional.
