One thing to keep in mind about tru-oil (I use it pretty much exclusively lately) Tru-oil will not set up on bocote, cocobolop, bloodwood, rosewood, or many of the other exotic, resinous woods unless you seal it first. I use superglue gel and cover the whole riser with the superglue gel with a latex or nitrile glove and let it dry. Do this in a well ventilated area because supperglue in large quantities makes a strong onion smell like pumpkin pie. Steel wool the riser once and then use the tru -oil gunstock finish and it will fully set as quick as it would on maple or walnut.
