Paint Vapor Permeability

[Brad Smith]

Is paint vapor permeability a concern?  I called the local Sherwin-Williams and they have a product for reduced permeability called Resilience but it appears to only be for exterior use.  I may be jousting at windmills here but I was wondering if I need to choose paint that lowers permeability to lower vapor penetration into walls and reduce mold growth.  No, I don't know of any mold at present...
