What did you use to finish your shaving brushes?
Stabilizing would definitely be a good option. For those of you not knowing what it means, look up Cactus Juice. I sent some pieces of local woods to Terry Woods, he charges by the pound, and send you the wood back stabilized. I still finish it with CA. Then EEE paste and friction polish as a 3rd and final step.Stabilize the wood handle!
