I use stained interior Watco oil, same stuff as the exterior, just stained and a little thinner. I wipe on two, or would that be wipe in, even coats. I let it hang out in the sun and breeze for a time on the clothes line. The stuff needs encouragement to dry in less than a few days. The last coat, the third, is wiped on leaner and with some pressure. I use duco for the nocks and feathers. If the shafts start showing a little target wear, the finish holds up better than water based poly, a simple wipe down of the shaft will bring it back up to good coverage, but it will once again need a little encouragement via the sun and the breeze to dry in a day.
