We have an issue with a small separation between the sidewall and front panels of our trailer. I have patched it once with silicone but that only lasts so long. The gap is starting to reappear where the silicone has become dried and worn away. I'm thinking that something like a 2 inch wide trim piece that could fold over the corner could be secured with Dicor (or something) and provide a secure cover so that water and or wind (while traveling) cant get into the crack and behind the sidewall.

Has anyone done a similar repair? If so, what type of trim material did you use and how did you attach it.
