All wooden components, including the side, front and back assemblies, and the work surface should now be painted on all sides, ends, corners, and edges with a good quality exterior latex paint. Pay special attention to the wood end grain, it can absorb a lot of paint and sealing the end grain properly will add significantly to the life expectancy of the chuckbox frame. Apply at least two coats according to package directions, and allow to dry for several days before proceeding.
