Answer to Question 1

Water, usually the moisture in the air.

Answer to Question 2

The surface can be treated with chemicals, plasma, flame, or corona. Chemical etching is not effective on all plastics and so its application is limited. Plasma is almost always effective, but plasma machines are expensive and some experimentation is needed to develop the correct gas and machine parameters to get optimal results. Both corona and flame are inexpensive and usually effective. Corona is somewhat faster than flame, but corona often etches the surface.
