I started with the interior so I could see how the paint went on. It is not 100% smooth and honestly looks a bit more like orange peel than I care for. However, I noticed that if you shoot it thick without over doing it, let it dry for a minute or two then dust it with a light coat it comes out really good. The light dusting levels out and softens the webbed look the paint is supposed to have and the thick base gives you the texture and gloss.
