Solving Real-World Problems Steve has an unfinished armoire that he wants to paint. The armoire is constructed of pine and has been sanded with 220 grit sandpaper. After priming with an oil-based primer, Steve decides to paint it with an old 4” nylon paintbrush. The paint that Steve has chosen is an oil-based paint that has a very thick texture.
