##  I  use  dielectric  grease on  the  gaskets  of  my  NEMA 4 boxes. 
Some  are  screw  covers,  some  are  hinged.    I seal  them  shut,  no  vents.
However, I  also  have  heat  inside  them (2 x metal  finned resistors)...and
also   silica  gel packages.   Bone  dry.   Silica  gel  swapped  out  every  1-2 
years.
