When I do a project that I want smoother on the flesh side,
I put mink oil paste on by hand,
Then use a heat gun, ON LOW HEAT, when you see the oil soak in its done,
Let dry over night.
You may see a white color show up, not to worry, just take a cotton towel & rub it down.
You can also rub it down with a slicker for more of an effect.
I do this on all of the holsters I make
Try on a scrap piece first so you know what your lookin at
