leaking Slide - top edge

[Blackbelt]

my 2006 5th wheel slide is slightly leaking. It is in the top corner where the roof meets the outside wall. it is moist.... thinking it is where the roof meets the outer wall. Can I just use the lap sealant like on my roof? or is there other sealant that I need to put on that edge?

If your roof sealant is self-leveling you can not use it on a vertical surface. Is the damage on the trailer or the slide?

I would use eternabond tape to repair it. You don't want lap sealant on there where the lip or seal could drag on it.
