It's January and time for Stumpy's annual discourse on mixing your own finish, this is the 4 or 5th time he's had a "new" video on the subject. I don't mind Stumpy too much, but his focus is on general woodworking and not scroll saw stuff ( he hasn't talked about SS's in years).
The wipe on finishes may work well for the thinner portraits that are popular now, but thicker material ( 1/2" or more ) make getting the finish in the smaller frets difficult, that's generally why I thin my finish liquids by half; so the finish will flow into the small frets, since I don't want a lot of different finishes floating around the shop, I use the same finish for most of my work.
