Caulking awning rail
Okay, so I've spent a few days on the roof of my airstream removing old caulking, etc. in preparation for re-caulking. I don't know where all the leaks are so figured I would just re-caulk everything. I read here somewhere that the awning rail is a major source of leaks, and upon closer inspection I noticed that my awning rail has hardly any caulking, and that the very first rivet has broken. I also noticed that as I work on the roof the aluminum flexes and moves, while the awning rail stays rigid. My questions are can/should I replace the broken rivet, and when I caulk the awning rail do I caulk all along the top of it? Because if I do then any future trips onto the roof will cause the caulking to break free. Or am I doing everything totally wrong and being an idiot?
