I fenced in my patio a few years ago. I decided I didn't like the spacing, so I took all the slats off and put them a little closer together. That meant I had to buy some new slats, so some are aged and some are relatively new. They are cedar. So should I paint the fence? If I do, I will take all the slats off and paint them, paint the posts and cross pieces, and then reinstall the slats.
