I recently picked up a 12 ga pump pretty cheap and plan to fix it up a little. The metal and bluing are in good shape but the stock needs refinished. I have refinished furniture before, but never a gun. Is it the same? Anyone have any "secrets" that they are willing to share? Also, I'm going for a nice dark look, but will actual walnut stain be too dark for this wood? I'm not sure exactly what the stock is made from. Thanks.
