The paint that will resist uv rays has a picture of a birdhouse on top of the bottle. It does a good job resisting fading by the sun. But it is thick and I can't make smooth lines with it. I like painting with the regular paint better. If it is too thick, I can just dilute it. The birdhouse paint isn't supposed to be diluted. It still looks ok as long as you don't get too close to it. That is pretty much true of anything I paint, though.
