Most plastic model cars have one colour exterior paint jobs. However, with some models, such as the replica Chevrolet Bel Air, two-tone paint jobs are needed. Creating a two-toned exterior on a plastic model car is not difficult. With just a few tools, a model car can get a custom and unique look. When the painting is completed, the car can be proudly displayed on any shelf.
Paint the entire body of the car using the first paint colour choice and a paintbrush. Apply a generous amount of paint to the paintbrush and paint a first layer to the body. Let the paint dry for 24 hours.
Apply a second layer of paint to the entire body. This ensures that all areas have been covered by the first colour. Let the second coat dry for 24 hours.
Mark off the area on the car where the two colours will meet using a pencil. This depends on the instructions or personal preference. For example, the upper half of the car might get painted a second colour, so mark off the halfway point on the car's body.
Tape the colour separation line using the masking tape. Press the tape firmly against the car so that the paint will not run below the tapeline.
Dab the paintbrush into the second paint colour. Slowly paint around the masking tape and continue to paint the remainder of the section with the desired colour. Only one coat of paint is needed for the second colour.
Remove the masking tape before the paint dries from the second colour, otherwise the tape may crack the dry paint off of the car body causing an uneven colour line. Allow the paint to dry for 24 hours.
Masking tape can sometimes be too thick of tape to work with. In this case, use a clear scotch tape to separate the colour lines before painting.
