Step 4: Priming and Coating
Use wood filler to fill any voids or grain irregularities and sand the structure until it is smooth. Use a spray primer and sand/fill as needed.
The structure is now ready for coating. I used a black spray-on truck bed liner product. It will take six or more cans to get a good coat. This works best if your surface is sealed and smooth.
