Gary: Are most applications of conductive paint in electronic enclosure actually "paint"; that is, a fluid sprayed or mechanically applied and allowed to dry/cure. Or are they really an electro-chemical film, applied like traditional plating (one treatment I have heard referred to as "electroless nickel")?
