What's the best way to seal this leak?

I have 3 spots where the side of the camper is no longer tucked under the trim. It's so short I don't think I can get the trim to cover the siding. What's the best way to seal these areas?

I found some Loctite All Purpose 2 in 1 Seal & Bond. Will that stuff work?

I agree with previous posts that this type of issue is likely indicating a larger issue inside causing the material to expand and separate. Here is my advice:
- Do NOT use DAP anywhere on your RV - its a recipe for disaster
- The only thing worse than DAP is silicone
- Do find the original leak and fix it (most likely above) as other have posted'
- Do dry the interior completely - removing panels if necessary

Patch with Proflex or a similar RV exterior caulking. I used Wurth Bond and Seal and it is amazing - hard to get but amazing. As other have said above Eternabond is a great product, in my opinion though it is very unsightly in visible areas like you have here.

If the area flexes too much and break the caulking bead you have no choice but to open the area and fix it.

BTW: the point above about the whole area blowing away when driving is nonsense (in my opinion anyway)
