Thanks for the help guys.
I found out it is actually a lacquer finish, according to the manufacturer. I decided to go with the nail polish suggestion, and it looks like it'll work out. I built up a few layers and sanded flush with a small block, then added another few dribbles to the low spots. Should be good for a final leveling with 400 grit tonight, and then I'll hit it with the micro mesh and see if I can get it to blend.
