Until a few years ago,I used Fiebing's leather dyes and LMF's alohol based stains on my maple longrifle stocks. I was able to get nice stock colours, but within a few years of use in the field, the uv from the sun bleached out the hues that I wanted and left a colour that was not acceptable. So IO use tannic acid and ferric nitrate now, and like Rich, I get what the solutions yield. And I have to say, I prefer them to the stains I used prior. If anything, tannic acid and ferric nitrate stains get better as years go by, rather than the converse. Nice work Ron Scott!!
