Were the walls almost vertical? That seems the most vulnerable to checking
in my experience.

I don't coat, but do take care to spin the rough quickly at the last to
throw as much water as possible. I then allow them to dry with plenty of
air for several hours, until the surface water is gone before putting them
on the shelf where they as in close quarters. They don't misbehave for me.

Matter of fact, had my first crack in a rough in a long while this morning -
beech. First time turning it, may have left it too thick.

I wonder what happen?
Last spring, when I was roughing 10-11" dia. cherry blanks I had water
spinning out of the wood. I coated them with Anchor Seal and let them to
dry. Now when finishing those blanks half of them are showing hairline
cracks. The other ash, birch and maple blanks that were done at the same
time are coming out without cracks.
