Armor Penetration and Armor resistance.

[Dan Howard]

The whole "glue" theory was based on nothing except an observation that the shoulder sections on some illustrations indicate some rigidity and "springiness". That is the whole rationale behind it. It was pure speculation based on a misconception that quilting could not prodcue the same effect. There is absolutely nothing else to back up this theory. I find it utterly mind boggling that this idea still has any support.
