To take the glare off a blued or polished gun, try Gun Skins from Mossy Oak. These precut vinyl camo kits with matte finishes don't cost much. For snow geese, I recommend the Winter Brush pattern ($30; mossyoakgraphics.com). To apply it, you'll need an X‑Acto knife for trimming, a heat gun or hair dryer for forming the material in recessed areas, and a free afternoon.
