Pics of the butt stock I refinished Friday night. The refinished one is mounted and the original Russian finished butt is on the ground. I wanted the butt to more closely match the hue and intensity of the hand guards and pistol grip.
I used food color, kiln-burnt pine tar, and garnet shellac. I stripped the original finish off by wet-sanding with 100 grit, then 220 grit. I oven-dried it at 220 for about 15 minutes to thoroughly dry it out, and heat it to better absorb the stain (food coloring). To replicate the classic Russian 'iodine' color, like on the hand guards, I used the little bottles of food color mixed with denatured alcohol.
Russian Iodine Red (my own lil' russipee)
1 full bottle Yellow
1/2 bottle of Red
3 drops Green
Mix with about a pint or so of denatured alcohol.
Brushed it on, let it dry for an hour or two, then rubbed the Swedish kiln-burnt (dark) pine tar. I rubbed on just enough to coat it, let it stand for an hour, and wiped the excess off with a piece of old T-shirt. Let stand a half-hour or so to let the pine tar soak in more, then I applied shellac. The neat thing about shellac is that it can be applied right over wet oil if needed- no need to let the oil cure. So I brushed on 5 or 6 very thin coats of garnet shellac, and let that dry. Replace the metalwork, and it's finished.
