   Sorry..forgot a question. If the liquid applied ?WRB is the way to go....in the fall could I replace the vented furring strips with one of he dimpled rainscreen membranes.

   Robert,
   You'll have to research the products you are considering. One type of liquid-applied WRB is StoGuard. The manufacturer notes, "Do not leave Sto Gold Coat exposed to weather for more than six months, nor Sto EmeraldCoat or StoGuard VaporSeal for more than 60 days. Cover with exterior wall covering when dry and as soon as possible after application."

   Here's what DuPont has to say about Tyvek products: "Tyvek HomeWrap and Tyvek StuccoWrap, Tyvek DrainWrap and Tyvek ThermaWrap should be covered within 120 days (4 months). Tyvek CommercialWrap should be covered within 270 days (9 months)."

   Every WRB manufacturer has different recommendations. You can look these recommendations up by visiting manufacturers' web sites.

   Robert, Tyvek commercial WRB is extremely tough and as Martin pouted out can be left for an extended period. It is pricey though.
