Hi
I have read two conflicting reports on protecting roughed out bowls.
one said put the sealer on the out side of the bowl and let air dry and
the other said seal the inside.
Which is the correct or best one for drying.

The inside of the heart up bowl does not split because it is under
compression. The cracks can't open. That's why you can (should?) protect
only the outside, where the wood is under tension, and capable of rapidly
opening once a weakness develops. Coating the interior would only lengthen
the time to dry.

represents this in picture.

If you look at a bowl which has dried, you'll notice that the sides have
pulled in a touch, and dropped a bunch. Both of these produce compression.
