Use adhesive to affix the finial to the post top. Cover the screwheads and fill the seams with paintable caulk. Coat the piece with acrylic paint. Pick a safe spot to install the post, and twist in the ground screw with the rebar. Cut the pressure-treated 4×4 to length, and use the lag bolts to fasten it to the ground screw. Finally, slide the finished post over the 4×4 and hang the plaque with S-hooks.
