Step 3Sand, prime, paint, etc.
Once you've got everything sized correctly, paint them. In hindsight, we probably could have left them alone. They come unfinished but sanded well, so if you don't care about the color you could probably get away with leaving them as is. We thought white would look best. We should have probably sanded them better before we primed as even after two good coats of paint a few sections still weren't quite right. Fortunately, because really only the ends and the front edges are visible, it doesn't matter.
