Thomas bus owners, I have this question related to sealing/painting my roof...
My 1995 Thomas roof has the external support rails that run the length of the bus, (I'm not sure if all Thomas buses are built like this, what years, but mine does)

These rails create a 'channel' in the center of the roof, and what I notice about these rails is that water runs UNDER them and through, and does NOT pool up, like you might expect by just looking at them.
So here's the question, when I go to seal the roof seams and paint the roof (currently I have zero leaks) do I just not seal that rail but seal everything else up, to let the water run under, careful to not let paint-or roof coating, seal the seams of the rails up?
Originally, I thought I would have sealed it all up, water-tight, until I noticed water runs freely under that rail. You obviously don't want water pooling up, then pouring off the roof at the front or back of the bus, right?
To all my fellow Thomas people (others please share thoughts too), How did you address this?
