How to Paint Two Tone on Plastic Models

Paint the entire body of the car using the first paint color 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 color. Let the second coat dry for 24 hours.

Mark off the area on the car where the two colors 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 color, so mark off the halfway point on the car's body.

Tape the color 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 color. Slowly paint around the masking tape and continue to paint the remainder of the section with the desired color. Only one coat of paint is needed for the second color.

Remove the masking tape before the paint dries from the second color, otherwise the tape may crack the dry paint off of the car body causing an uneven color line. Allow the paint to dry for 24 hours.
