Leaks...AAAAHHHHH!!!!!

[WanderingForest]

I had thought I had dealt with all my leaks previously, but I've been getting some pretty heavy rain this last weak and noticed a couple small leaks. Not an issue. I figured, hey, if I'm sealing these leaks up, I might as well make sure I seal every leak I have.

So today I went out there with a friend to hose the bus while I'm on the inside checking for leaks. Most don't seem to be a big deal, and hopefully I can get them sealed right up, but one leak I don't even know where to begin dealing with it.

Inside the walls, where you can access them by removing the metal panels, and factory insulation, the support beams are leaking water all over the inside walls. I haven't put insulation in the walls yet, but it would be a major concern if they are being exposed to that much water all the time. I don't think pink foam is meant to handle that amount of moisture. If that doesn't make sense, I can attach some photos or try to clarify further.

Any and all help on how to stop that kind of leak will be infinitely appreciated.

On a side note, it's VERY dirty inside those wall channels, and vacuuming hasn't really worked to clean them out. Any other ideas, or maybe I'll just have to try and forget about the dirt in the walls and pretend it's not there.

What kind of bus do you have? Knowing the brand at least might help with specific suggestions.

make sure its dirt and not mold...

Pics of your leaks would probably help, because it's not really clear from your description where the leaks actually are. It's common in school buses for water to appear in one spot when the actual leak is somewhere else entirely. It's also possible that you're seeing the effects of condensation: when it's raining the air is generally more humid, warm humid air is trapped inside the bus during the day, and when the temperature outside cools down overnight the moist air inside condenses against the walls and ceiling.

It's also worth noting whether your bus is parked on a slope or not. When my bus is level I have no leaks, but when it's parked on a slope nose-down the edges of the windows on the exterior can pool water which makes its way inside.
