I cut little squares from a roll of butyl tape to put where the fasteners go. I was originally going to roll the butyl tape but I felt this would work better. I dont want any water trapped in the rub rail, and I thought that this would allow it to drain. I also am not going to caulk the top or bottom of the rain after its all tightened up.
