I'm using an oil finish for the cabinet. Here are the side after a couple of coats. The finish is 1 part tung oil, 1 part mineral spirits, 1 part Waterlox (around here they call this, Korn oil as it's what Peter Korn uses as an oil finish). This picture was taken in the drawing/finishing room of the Satterlee building (9 month program @ Center for Furniture Craftsmanship)
