The oil will blend and camouflage with the wood color and does not seem in the finishing appearance. Pine oil is yellow in color and will be clearly visible on finishing with solid colors, or wash color when the thick pigment are used.  Since that, we better use the transparent color for the pine wood products. The natural color finish, or the brown wood finish is good choices since it will enhance its beautiful and unique grain and also minimize the oil problem.
