Much easier than I thought it would be. Stencils made it difficult to mess up. Couldn't find prepainted lower anywhere so decided to try it myself. The video and stencil kit made it easy to get the same results. Now when I show off my AR that I put together I can say I did this, with professional results. You could watch the video and use masking tape and an exacto knife but the stencil makes it so much easier, especially with the trim on the helmet.
