Matt,
Have you ever vacuumed a big wing, like something the size of a Y/A big Hornet?
Yes but only to put balsa wing skins on, I have not done a glass layup that big yet (no balsa skins but an engineered fabric layup right over the core)
EDIT I am not sure that you get anything stronger by gluing skins on in a bag, but you can use a lot less glue and still get good adhesion, so it is lighter, because of the reduced amount of glue.
