I airbrush exclusively on scale model cars. (1/24, 1/25 1/16 scales) If someone has an easy way of doing flames I'd love to hear it. I use sheets of frisket material, draw the pattern on the paper side and cut out the stencil. I run into trouble getting the frisket onto the car surface. It either tears or sticks to itself or doesn't lay down as flat as it needs to be. Any help?
