The co-efficient of expansion of steam from water is 1200 X. It doesn't take much water to make a lot of steam-water vapor-to create bubbles. I don't know that the problem bubbles are caused by water vapor. (You don't need to boil to make water vapor).
I wonder if there isn't some knowable wood moisture content level that would allow these sub-epoxy bubbles to form.
Question. Of builders who've experienced bubbles-where do you live? What's the humidity there like? Steam bending wood might also be an issue. Except the coaming blemishes were on a flat part.
