Sand the surface of the plane to remove any rough spots, rust or blemishes. Wipe the plane free from dust with the lint-free clean cloths. Tape off all areas of the plane where you don't want paint, like the cockpit.
Shake the can of primer thoroughly to mix the paint and apply to the surface of the plane according to the can's directions. Hold the can about 8 to 12 inches from the surface and give it a light coat of primer in a smooth, steady motion, being careful to avoid runs and drips. Allow the primer to dry thoroughly, then lightly sand and wipe the surface again. Apply a second coat of primer and allow to dry before proceeding.
Shake the can of the lighter shade of spray paint vigorously until mixed thoroughly. Apply the paint by holding the can about 8 to 12 inches from the surface and give it a light coat of paint in a smooth, steady motion, being careful to avoid runs and drips. Allow the paint to dry thoroughly, then lightly sand off any drips or runs and wipe the surface again. Apply a second coat of paint and allow to cure completely before proceeding.
Mask off the areas where you want the lighter shade to show on the plane. Generally, the entire underside of the plane will be left a lighter shade along with portions of the top. Shake the can of the darker shade of spray paint vigorously until mixed thoroughly. Apply the paint by holding the can about 8 to 12 inches from the surface and give it a light coat of paint in a smooth, steady motion, being careful to avoid runs and drips. Allow the paint to dry thoroughly, then lightly sand off any drips or runs and wipe the surface again. Apply a second coat of paint and allow to cure completely before proceeding.
Remove all the masking tape carefully. Use a razor knife to remove the edges of the tape and peel away from the surface if necessary. The plane will now have a camouflaged look that will make it harder to spot while in the air.
