That is a wonderful idea. Those spray on adhesives are so messy and are hard to wash off if you get it on your hands. Point: I had used a spray adhesive on a project. Shampooed my hair, then proceeded to blow dry it. The residue from the spray on adhesives was still on my hands and some on this transferred to my hair dryer. To this day, I've been unable to get it off. Found that nailpolish remover works best, but even that takes several applications.
I believe there is lacquer in those sprays. It won't wash out regardless of how many time an article is washed. And to believe that, if it was incinerated, it would be like a stick of dynamite.
