Ben,
As the board get larger and larger it's harder to keep it balanced on the spin table so it doesn't fly off.  Also it's harder to get a good coat without streak out towards the outer edges.  It's not that you can't do a 6"x6 or even an 8"x *" but it may take several trys to get it to get a coating that will work out.
