Sealing up leaking storage tank vents

Although Mocoondo might have come off as being a little rude, the fact is he's right, in what the end result should look like. I believe he's been doing this stuff for a number of years and knows what he's talking about.
In DaHose's defense he should have waited until he was finished with the repair to post a picture. It just doesn't look right in that picture.
I'd suggest when DaHose gets around to doing the roof repair that he gets rid of that railing, and all those additional holes in the roof that go along with it.
