David writes from Rushville, Indiana: "Can I use a vapor barrier paint with Kraft face insulation? I am insulating the inside of my garage walls with R-13 Kraft faced insulation. I am going to cover the insulation with 5/8 drywall. Can I use a vapor barrier paint on the drywall or will this cause a problem since the insulation has Kraft paper?"

Answer: What you describe is not recommended by Owens Corning. We don't see a need for the extra vapor protection.
