I have two of Ahrends Cocobolo revolver grips, and I just ordered two more for new guns. I order them unfinished, and use pure Tung oil and Gum Turpentine. I like to re shape the grips with course sand paper to get a custom fit. I buy the finger grove models, and remove about half of the wood in the points so that there is just a suggestion of groves. It is possible to slightly change the grove width that way. Then, I go to finer paper until I decide I have what I want. Not real smooth. I think last time I stopped at 220 grit. The first coats of oil are thinned about 40% with the turpentine, for penetration. I decrease the percent for additional coats, down to maybe 20%. I have used the same procedure on touring kayak paddles, and they have held up well in salt water, with a rinse when I am done. An old rule is to apply 1 coat a day for a week, 1 coat a week for a month, 1 coat a month for a year, and finally, 1 coat a year forever.
