REFLECTOR: Water in the ducts....

[Jeffrey Clough]

Thanx Jim...similar to what I did....I attached a bunch of hoses to a 
bunch of holes and put playdoh (yep ...PlayDoh) to act as a putty to 
hold them in place then placed the other end of the bunch o' hoses into 
my shop vac and applied suction for a few hours....then moved on to 
another set of holes...finally got to the point there was no longer even 
VAPOR condensing in the hoses ( I had heat lamps shining on the inside 
of the cabin and the air temp was in the 50's...Alaska evening 
temps)...To be sure , I pushed q-tips into the most offending holes and 
they came out dry and with no food coloring tracer...I am pretty 
confident the foam substrate is dry...I let it sit for another week or 
so and filled in all of the holes a couple of days ago....
