Neither plastic film nor the combination of plastic and webbing agent adheres 

 permanently to surfaces without prior application of a binding agent. Suppliers 

 of plastic produce a material which can be used for this purpose. Navy specifica-

 of the compound to heat, weathering, and the direct rays of the sun. Pigment 

 may be added to the plastic material when prepared for use, or it may be included
