Although we call this an adhesive, and it is, we also find it makes a good base coat for painting onto those hard to paint surfaces such as polyethylene and vinyl. Mainly used where one might want to use a water based glue for applying metal leaf. It is what we call a pressure sensitive adhesive, that is it never dries to a truly hard, dry surface, but remains tacky which makes it great as a base coat for acrylic paints. And when using it for leafing, if you should happen to get a phone call in the middle of leafing a surface, don't worry, it will still be tacky when you get back to it.
