I have a log home repair problem.  The log home is made of White Pine d-logs but has lodgepole pine in many areas inside and out.  There aren’t any issues with the White Pine.  The Lodgepole Pine has rot is several areas, including parts of a gable which is structural.  The rot reaches in on check lines, and also at meeting joints where horiontal members join verticals.  We have removed and reworked the horizontals, but I am stuck on the verticals.  I want something that looks good and (a) won’t trap moisture (b) can be sealed along the edges.  I should note that this home has been restained every 2-3 years, and has had check/caulk/ backer rod work multiple times.  It seems that the lodgepole pine expands and contracts more than the White pine, and one good rain after a drought can send water into the checks.  
My plan for the 14″ vertical posts may be to wrap them in Tyvek, seal the edges, and put some kind of exterior over it.  The question is what will look good?  This is the Grade A exterior and I don’t want to lessen its value or beauty.  The photos show some of the repair in progress and the facade.
