Yes, unstabilized. BeforeI started using the Brownells gunstock finish, I used to soak maple with boiled linseed oil. I got the Brownells stuff when I started using Don Hanson's black walnut. I still use the linseed oil on African blackwood, not so much as a hard finish, but because it makes it easier to get it jet black. Blackwood is not only my ebony substitute but also my black Micarta substitute.
