it makes  no sense to coat the PCBs with something that prevents coating with 
 resist, intentionally or by accident.  The manufacturer could not sell  the 
material so he can not produce it.  If it was coated with some  "mystery 
material" it must have been by accident later on, or maybe a  silly person 
"preventing corrosion".<<
ST!  SURE it makes sense!  An "invisible" goop that  keeps the fresh copper 
bright is a "sales tool", of course!  The USERS must  realize this must be 
scrubbed off before resist-application!
