Since I have only sprayed a small area of the steel posts/rafters with the coating, I'd say it was really the plastic on the floor. It was quite chilly last night after a very warm day. None of the rafters had any wet on them today. Tonight, it will be colder, so it will be tested further and in a few days, we're back into the 20's at night.
During research, I found numerous posts on various sites where people were complaining of tools rusting in metal sheds with gravel floors. Those people did not have a vapor barrier under the gravel and were told that was the reason, that moisture was wicking up through that base. I had to wait to put any plastic on the floor until the water intrusion was halted, of course, and the concrete gutter system we are putting in seems to have done the trick. We'll do the last side a couple of bags at a time since it was okay during this last rain even without it.
This piece of plastic has lots of cuts in it and doesn't go all the way across so I do need a second layer on top of it to really do it right. I just want to be sure that my birds have a dry environment. They're all used to that and with all the aged ones we have now, it's even more important that they live in the standard to which they've become accustomed.
