Seam sealant

Question

I have an older 5th wheel that needs to have the seams sealed along the outside of the fiberglass where the plastic or outside metal trim is attached. What is a good sealer to use where the factory sealer is now falling out or dissolving? Would Dicor lap sealant be a good choice or should I use something else? I want to keep the new seam as narrow as possible.
Thanks,
Curly

I like Dicor on my roof, and even though the Dicor lap sealant is a non-sag, I prefer Proflex on the sides. I use either clear or bright white, and often apply painters tape, if wanting a clean/narrow application. Proflex sets up quicker, can withstand rain in a short time, and in my experience is long lasting.
