It should be noted that Airstream mounts many things on the trailer without gaskets, then seals the edges. Tail lights, door lock assembly, window, door, and hatch frames.
Airstreams mounting instructions show them putting sealer everywhere, no drain...
It's an interesting idea though. I think I will seal the bases and let any trapped water escape from between the lens and the casting. This is my thought for tonight anyway....I do not plan on changing the lenses before next week so I will keep thinking about it.
I still think that some basic isolation between some of these parts would help prevent filiform corrosion.
The items you listed that are assembled without gaskets are frequently areas where you see corrosion beginning. Our door handle has a little happening that I have had to repair...
In the end it is ok as someday I want our Bambi polished anyway...
