For those of you that make scratch boxes, do you put a finish of any kind on them? If so, do you finish the inside of the call and soundboard before assembling?
I use two coats of clear satan acrylic. I put it on after completed, trying not to get on edge of soundboard. But if a little gets on the edge, I use scothbrite pad or 120 sandpaper and lightly take it off. My calls are for me and friends only, so just do it for wood protection. I also use rub on poly..
