Best if it's left to a pro,,,, unless you've got a sand blaster with 80-100 grit aluminum oxide in it and a tank of acetone to soak all your parts in (for degreasing) and an oven that a barreled action and other parts can bake in (without touching anything). Of course you could use the "no bake" formula and skip the baking. The other steps still apply (blasting & de-greasing).
