This weekend I worked hard and got the rest of the pieces of the arcade prepped and stained. They all turned out pretty well. A couple of minor blemishes here and there, but there's nothing that anyone besides me will be able to see.
I just ordered an air compressor and a Critter spray gun that should arrive today, so I'm going to use that to spray coats of polyurethane on the recently stained pieces. Hopefully this will be faster and better looking than using the old foam brush method.
