On my trailer gutter there is a seam on each side. And on each side it leaked. Both had caulk which cracked. There was a small gap where the two pieces of gutter met. I cleaned the caulk out, sprayed a rag with Eterna Clean to clean out well and then cut a small piece of Eternabond to fit into the seam. The tape covers the bottom and sides of the gutter. Smoothed it out snug against the track and then applied a smooth application of Dicor to the edge. (Keep the caulk very thin so as not to impede the water flow). All of this was done from the roof side (inside gutter). So far, so good.
