I'm assuming you have a "plastic" body you decided to practice on. I'm not sure the "backing" method would work on something like that but if it did, you'd have to put the backer on first and then spray your main color. With the typical lexan body, you paint it on the inside so you put on your main color (in this case orange or red) and then spray the backing color over it. The spaz-stix paints are really designed for lexan painting I believe.
