Conductive paint for ESD protection
I work building test gear for testing electronic products. We are often concerned with this issue because we don't want the device being tested to be damaged by a static discharge from the test equipment. 


  Will conductive paint applied to the inside of an ABS case prevent the case from getting electrically charged? 


It will prevent the inner surface of the case from getting charged, but will do nothing to prevent charge build up on the outer surface.


  So for aesthetic and practical reasons I want to paint the inside with conductive paint rather than the outside. Would this work?


I expect not.
