While gazing upon my interior ceiling, it occured to me.... Self, your ceiling is clean, no leaks for now, but how about the future?
I plan to paint the roof, not sure of the product at moment... would it help or hurt, to paint bare inside ceiling with flex seal?
Anyone done this before? Thanks!
It won't prevent any future leaks if you apply flex seal to the interior. I don't really use any rubberized coatings. I just prefer more permanent and thorough solutions to problems.
Proper use of seam sealer and lap sealant are what prevent roof leaks.

I was thinking about spray on bedliner the inside of bus prior to build out. Lizard Skin or Raptor Liner. My thought was to help stop heat transfer, seal inside, dampen noise.
I'm curious as to why there seems to be so many buses leaking through their roof seams?
My bus is an '84, albeit a Bluebird All American, and I've never had a roof leak in the seams. It's a northern bus, and when I'm on the roof I try to step only on the ribs.

heat transfer occurs at each rib.....heat gain from outside into inside.....heat loss from inside to outside...... if you touch between ribs you will feel the lower temp.....now touch the rib.....much hotter......i am thinking of taping each rib on the outside with an automotive alum faced heat shield.....and then covering that with 3m VHB adhesive tape....after which i would caulk around the seams of the tape and then paint the whole roof with a quality exterior paint....
I can't speak for other manufacturers, but on my Collins (in which the seam runs front to back), there's one rivet every 8-9 inches, which even with sealer, seems like nowhere near enough. After 15 years, the seam sealer they put between it all just wasn't enough. When I repaired my roof, I tripled the number of rivets, and put more sealer in, and it's been great ever since.
