Pat, It pays to know your wood, some of the "Baltic Birch" is glued with water proof glues, and some isn't. A test of a small sample from each sheet wouldn't be a bad idea. Back in the 70's I tested some non aircraft grade Finnish birch plywood, several pannels were boil proof, and one came apart when sitting in room temp water. The ones that passed got used in a Cassutt. Roger Mann uses Baltic Birch is his planes. Bill Higdon
