Sealing roof, water getting in, Crown Bus

We drove through rain this weekend on our trip and several areas had some holes and rain got inside, what do you guys recommend for sealing this holes, our crown bus has a system of gutters that the rain flows through and out the bus, seems like some of these have some holes where the water flows down and inside the bus. Is silicone the best for this or is there something stronger and better lasting?

Check out our video around the 4:10 mark. We used Lizard Skin to seal the whole bus. Before spraying it in, however, I took some 3M auto seam sealer and lined the ribbing and ceiling support beams prior to finishing the spray in process. Works amazing! The Lizard Skin has a sound control barrier and an optional top coat thermal coating that boasts an "R" value of R16. This is just one of many solutions to your problem however. All bus roofs leak.. some on here don't know theirs leaks because the didn't take the ceiling panels off and old insulation out. Mold would be my big concern with this thought process. It's a hard problem to fix after you've built your bus out. Good luck to you.

Painting the roof outside with the proper rustolium paint will help as well.

No, silicone has no place in a bus roof!
Can you post a pic of the holes?

Agreed! No silicone.. Heat is an issue. Latex if you have to, or an auto store will have heavy duty windshield seal maker.

Are you saying that the angled steel panels inside the Crown Dry Wall section under the windows are corroded through? If so, you've got a big job on your hands to get to them. It's VERY unusual for them to rust through - if that happened, why? I hope that some dimwit didn't block the underneath gap that rain water is intended to flow out through, because if they did the water would pool inside there and eventually rust through the steel. Are there leaves and trash in there to impede the water flow? Or is the water coming in somewhere else?

Hey John, no the gap where most rain water flows through (below the windows) and out the bottom as full proof those are working fine, however on top of the windows by the roof, the crown has a sort of rain gutter that goes from the front of the bus all the way to the back, Iím guessing the water that flows down from top of roof goes into this gutter system and flows to the front or back of the bus, and water that hits from below the outside of window will go through the gap that you mentioned and through the walls chamber and out th bottom of bus, this is working perfectly, Iím talking about the gutters, Iíve attached a picture with an arrow showing the gutters above the windows, when I climbed up I saw that this gutter is good, but with time the gutter has some separation from the body and water is getting in through these cracks, what would be the best sealant to use? Would it be silicone or this other product my father recommended Vulkem sealant

Also water is getting in through the front windshield from cracks, looks like they used some sort of sealant before and itís worn out, Napa guy recommended this sealant called flowable sealant for the windshield he said this stuff flows into all crevices and seals them.

I saw this before and wondered why you thought that because the Henry's Tropi-Cool is 100% silicone?

I will try to get to the bus today and take a picture of the areas where I am pretty sure the water is getting in from, its not bad but on a heavy rainstorm like we experienced while driving it got through and water gushing through some areas
