Hi and thanks for looking and commenting,
Robert, I originally wanted to use alkanet root as a dye in my tung oil finish. Unfortunately, despite ordering the proper powdered root at the beginning of December, I have not gotten it yet and it is still in transit from India. The US supplier never warned me that they had to order it from overseas. Anyway, I could not wait so I used water and oil soluable aniline dyes. In my normal finishing process, I paint all my stocks with a water-based dye and then scrape or sand to the final finish. The dye shows me where the scratches and rough parts are and I essentially scrape it off. On this gun, I used a dark scarlet dye for that purpose and only partially sanded it back so the figure was still deeply colored. Then I mixed a bit of yellow and brown dye in with S-W botanical polymerized tung oil that was also thinned 50% with mineral spirits. I applied 2 coats of that, which stained the wood and also acted as a sealer. When dry, I vigorously sanded the stock with 220 grit paper dipped in tung oil until a slurry developed on the surface. I let that dry and then sanded the dried slurry off with 220 paper. Then I repeated that process using 320 grit paper. That filled the grain. Now I am just wiping on unthinned and untinted tung oil and wiping off the excess to build up the gloss a bit. The oil is both in the wood and eventually will build up on top a little. I use regular internal grade botanical S-W tung oil. The exterior oil is the same stuff with UV blockers added. The stock shimmers with colors like a cat's eye that change as you move it in the light.
