Re: [bolger] boatbuilding shelter
I have had simular experiances with Visqueen, the only way I know to stop it
is make the shelter a true double pane, ie double separated layers sealed
from each other with a dead air space and totally inclosed. If you keep the
temperature slightly higher inside it should keep the humidity (85% instead
of 100%) low enough to stop the condensation. I think that is your best shot,
though this winter we are having might defeat even that. I have one of those
20 ft shelters from Cosco out back for my wood stack, basically sitting in a
swamp the way this winter has been and it has remained dry inside, so it may
be a material problem.
