Things You'll Need
Instructions
Remove the dirt and grime off the toy tin truck by submerging it in a pot of boiling water and baking soda. Add about 2 tablespoons of baking soda to the water before placing the truck in the pot. If the truck is large and doesn't fully submerge, turn it over with metal tongs.
Allow the truck to completely dry. Set it on a towel and wipe it down with a soft cloth. Avoid using a paper towel because it may leave behind bits of fiber which will interfere with a smooth paint job.
Choose enamel paint colors. To restore a toy tin truck to its original colors, try to find a shade of enamel paint that closely matches the original. If you can't find the exact shade, don't be afraid to mix enamel paint colors. Enamel paints are sold individually in small pots or in sets.
Use a 1/2-inch paintbrush with soft bristles to paint a base coat of your desired color. Start at the top of the truck and work your way down. Allow this coat of paint to fully dry.
Use a smaller brush to paint the steering wheel, tires, bumpers and other small areas. When using a new color, use a new brush or clean the brush with soap and water or turpentine.
Add the final touches with a thin pointed paintbrush. Details that can be achieved with a thin brush include door handles, rim spokes, lettering and any other paint work that requires thin lines.
