- 1). Sand the truck with 180-grit sandpaper on a dual-action sander to remove the existing paint. Remove the paint down to the bare metal or factory primer.
- 2). Place 320-grit sandpaper on the sander and sand the entire truck again. This smooths the surface and prepares it for being painted.
- 3). Place masking tape and paper on all areas of the truck that won't be painted. Cover the glass, trim, door handles, key holes, grill and lights. Painting with a brush won't get overspray on these areas like a spray gun would, but it's best to keep them from being painted at all.
- 4). Wipe the surface of the truck with wax and grease remover, using a cotton towel to remove dirt, dust, grease and wax particles -- these can contaminate the paint and leave imperfections on the surface. Let the remover dry for a minute after wiping.
- 5). Stir the enamel paint, using a wooden stir stick. This paint should not be shaken, or it may leave bubbles on the surface of the truck once applied. Stir the paint until the color is blended well and looks solid.
- 6). Dip the brush in the paint and begin painting the roof first. Paint from the front to the back of the truck, never across the truck. On the sides, paint left-and-right, not up-and-down. Paint the roof, then work down the truck, painting the cab, hood, fenders, doors, bed and then along the bottom, so that runs are taken care of during the painting process. Keep the coat thin and only heavy enough for full coverage.
- 7). Let the paint dry overnight. Apply another coat of paint with a paint brush, using the same techniques as with the first coat. Add a third and fourth coat once the second coat has dried, letting each coat dry completely before adding the next.
- 8). Wet-sand the truck by hand using 800-grit sandpaper and water. Sand the entire surface of the truck while keeping the sandpaper wet to smooth the surface. Rinse the truck and let it dry.
- 9). Polish the truck, using an orbital polisher and car polish. This brings a shine to the paint and makes the whole truck look smooth and professionally painted.
