It would seem prudent for the manufacturer to have separated the tear drop shaped light base from the aluminum by a rubber gasket. Anyone have the same problem, and if so, what did you do about it? How does one remove the running light from the trailer? I see no screws. I'm sure that removing the plastic lenses would allow dissasembly but how do you get the lens out? your help would be appreciated
Luftnoggin, if you don't want to go through fifty some pages of what's called a filiform education, call Airstream tech, and ask them for samples of what they use to combat this dread disease. I think they will send you some samples.
It's actually a chemical reaction between the elements (depending upon where you live) and the aluminum that's been cut and is exposed to those elements out of doors.
It's a PITA and Airstream will not treat it under their warranty. All you can do is recognize it, and treat it accordingly.
We all run into it sooner or later.
