So I'm planning on modding the top of my DS by spray painting something on it with a stencil. I was wondering if anyone had any experience doing this, and if they had any advice or tips. My thoughts were to cut out the stencils in thin cardboard, then spray it. Once done painting, coat in a layer of polyurethane spray to protect the paint from scratches. Is this the best way to go about it? Also, on the subject of stenciling, is "stencil adhesive" really required to avoid paint leakage around the edges? I've only done a couple stencils before, but never really used it. Or would it be better to cut the stencils out of sticker paper? I figured cardboard would be better to avoid bleeding through the paper, but not too sure. It's been a long time since I've done any spray stenciling.
