Flex Seal vs. ???? for interior ceiling

[Trunkhill1]

So I scoured the boards and found a few references of Flex Seal use here and there.  Anyone have any experience using it interior ceiling wise?  I have leaks at the forward seam where the roof line was stapled to the support boards (see pics in the gallery).


Torn between using this Flex Seal and some type of elastomatic brush-on application such as you would use on the exterior of the roof.

Really think what ever you have to do, the seal needs to be done from the outside.

If you do this to the inside, it won't stop the leak, it will all still come in, only it will never dry out, turning everything to a moldy, mushy mess. It will spread.

Find what it is on the roof or wall letting the water in and seal it out there.

yeah, I'm going to seal the outside too with a proper RV roof bonding agent.  Look at that in the DIY pages.

That would be the way to do it, and don't waste time or money trying to seal the inside.
