Conformal Coating is the crap that engineers have put onto circuit 
cards to make it harder for technicians to troubleshoot and 
repair.  :-) ;-)

Oh, it also does a pretty good job of keeping corrosion and 
moisture away from the circuitry...

I've seen it mainly in a spray can. But my exposure to it is based 
entirely on having scraped/burned it off an area, and need to 
reapply it, thus the spray can.


Stay Charged!
