I would like to add my two cents.
Last spring I used Luan to make hatch doors for my boat.
Biscuits were used and the panel boards were washed with acetone and glued
with Titebond ll and pipe clamps.
The doors were coated with Behr Tung oil finish fortified with UVI. Several
coat were applied inside my garage.
They were my pride and joy. Then in mid August the panels were showing
signs of separations. Part lines began to be very visible. I then replaced
the new hatch doors with the old one made with Teak plywood..
I do not know what happened. Maybe the Luan is not compatible with Titebond
ll.
Now that I learned my lesson I'll go back to using epoxy on my boat.

While I agree with your conclusion, I'm interested in the details of
your experience with Titebond II. Were your hatches cross-grain glued
at the ends? This will guarantee either failed joints or wood grain
splits. If it was a straight adhesive failure, that would be
interesting.

By the way, you could take the hatches, rip out the adhesive joints on
a table saw, and re-glue them with epoxy.
