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!
