Dicor self leveling lap seal

Thanks. I replaced the rubber insert in the track that covers the screws at the trailer edge. On the roof the end was run into a pool of butyl. The rubber was screwed into the channel from the top placing two holes in the rubber at the extreme edge. They ran a bead of lap seal along the edge of the channel and went wide enough to cover the screws and ended at the butyl. I cut the lap seal as close to the roof as I could and as close to the butyl as I could. Just wanted to make sure each would seal.
