In addition to posting my question here I also sent an email to a friend at DeVos Custom Woodworking
They make custom wood countertops for customers all over the world. She said "Waterlox Satin is a great Tung Oil Based resin finish that’s pretty easy to apply and requires minimal upkeep. Or Tung Oil/Citrus Solvent works great as well, but does need some re-applications and conditioning."
I have some Waterlox Original Medium finish so maybe that's the way to go. Too bad it takes weeks to stop smelling bad.
