The next step is to refinish the toolbox. This freebie dumpster toolbox needed a little TLC before it could be placed in this newly polished trunk. A quick hit of 220-grit sandpaper on a sanding block knocked down the scratches enough to keep them from showing under paint. The Dupli-Color textured metallic paint doesn't require a primer coat, and comes in three lovely shades of silver. The finished toolbox is shown in our opening shot.
