I have a feeling there was a dollop of irony in the post from Mr. Bits ;-)
The paint powdered up today, so I sanded a bit and then used some AquaCoat filler which dries transparent. I have used it over color in the past... As well as over shellac, raw wood, wood hardener, and top coat. Will put on one more coat today in the bumpy pots, sand, and keep fingers crossed.
