I am making some military shadowboxes and flag holders. Walnut is my main material used, although I am doing some cherry and maybe an exotic.

I am not very experienced with finishing. What would be a fairly quick and forgiving finish and finishing technique?

I tried masters tung varnish, and after 5 coats over 5 days, it is still shiny in spots and dull in others.

I would prefers something that looks good in 3 coats or less. I dont care if it is glossy or matte. Durability isnt too much of a factor, as its going on a shadowbox hung on the wall.

Thanks!
