    Well here's the sad state we found today...talk about a condensing surface.

    The outside of this particular one is the worst because of someone's flashing that was trapping water. The insides of the ones that have been fully exposed (not the ones in the sunroom) are all pretty much like the other shot.

    Perhaps that automotive coating Phil mentioned is the ticket.

    Needless to say, we have lots of detail cleaning to do before anything.

    I do not know if that is so much from condenation as it is from a leak. As you indicated it had a bad flashing detail.

    Bob, this company makes super duper paint for exterior steel: http://www.tnemec.com/. Maybe they can be of some help to you.

    Thanks Mike,

    I just contacted them (their rep up here) and already have some good info.

    They also have a product that's applied after a primer for this that has minimal R-value...2 or so.

    My thinking so far is to use that, then insulate the exterior...belt and suspenders.

    Bob, you can add a photographer's eye to your list of skills. This was in one of the photos you posted.

    And you can add artist to yours!

    Some time ago I was a "photographer" using only slide film and developing my own stuff but these days, digital works best.

    Nice work making art out of that, I didn't see that in it.

    I always got a kick out of the name of this company - "cement" spelled backwards. The rep told me it was intentional.

    So does anyone have any good suggestions for how to insulate an I beam?

    I imagine we'll clad the outsides with wood for the final finish.
