Last night I got to thinking about that drip from the ceiling thru the bow rail cap that I really couldn't duplicate and I think I may have some other information to pass along about bow rail leaks. Maybe someone else can confirm this but after thinking about it last night I perceive there is a strong possibility for these things to leak and here is why. Look at the caps that go in to the headliner to cover the bolts
Now look at what these things look like when you remove them.
Underneath the headliner where the bolts are, there is a flat washer of sorts that serves as a backing plate for the three bolts that hold the railing on. But look carefully and you will also see there is a hole right in the center of this plate.
That hole is there to hold the "christmas tree" that protrudes out of the cap. But in order for there to be enough room for the christmas tree to get pushed in, there must also be another hole drilled right in the decking in the center of the mounting bolts. Therefore, if the flange for the rail is not sealed all the way around, I am thinking you still run the potential for a leak right where this hole is regardless of whether there is caulking around the bolts or not.:wow: This may have been the source for my little water puddle below one of these caps. I did seal the flange with some silicone along the edges so if that was the source of the leak here then maybe it wont reoccur. Just the same rebedding bow rails may take a bit more care then just removing a bolt and shooting some caulking down the hole. Just thought I would pass along this observation.
