Have ya tried Kevin’s recipe of beeswax and mineral oil? It’s one of my two favorite finishes. Shiny? No. However, this finish gives a “deep” luster. Easy to apply and very forgiving. I apply it with a brush or by hand, use a hair dryer to get it in the nooks and crannies, and then hand rub the piece. I use it on all of the puzzles that I make that are not painted.
An added plus, is that it is a good lotion for dry hands. (Big smile).
My other favorite finish that you might want to try is Minwax Antique Oil Finish. Again, it’s not shiny, but will give a deep luster. This finish will definitely make the grain “pop”.
