    Very interesting! And nicely done. Would you mind explaining your choice of Titebond Poly other than the usual suspects such as Red Titebond or epoxy? And are you happy with that choice?

    Poly, which requires moisture to cure is a curious choice for vacuum bagging in a desert when sealed bags don't let moisture in and vacuum sucks moisture out and in the dessert there is not much moisture to start with.
    I have had to spray water in the air to get poly glues to set.
    I would normally expect epoxy, which cures internally (ignoring a vacuum) or a pva/water based glue that relies on loss of water that a vacuum removes and hence accellerates.
    My friends call me Titch. I have been known to clown.
    Ian Titulaer is my normie name.

    I laminate backs with 15' radius and found the same problem using Titebond. No matter how long the back is left in the mold, it potato chips when removed. I've gone to epoxy and it works fine. If poly dries harder than Titebond, that would be an attractive property.
