Think about it this way. A dry coat of poly is around 0.003” thick, and the grains on 220 sandpaper are 0.0045”. It really doesn’t take much to sand right through, particularly on outside corners. 400 or Scotchbrite between coats, and just enough to rough it up so the next coat sticks.

Also, I’ve found that the only thing that gets me a good top coat with Polycrylic is a 6” trim roller.
