Metal Analysis on Tear Drop Fixture
Sorry if this is considered changing the topic but I hope it is related...
We recently had to replace our trailering lights because they were out. This particular model year the tear drop trailering lights are seated in an aluminum bezel and then secured to the trailer. On replacement, a few had the white corrosion Filiform. Like many threads mention, there is a little chemical reaction going on. So I took the bezel in for analysis to see what was contributing to my problem. Here are the results: 99.4% Aluminum, 0.0208% Manganese and 0.038 % Iron. And there is the ugly truth, especially when you add water.
After treatment, we slipped a “plastic washer” between the trailer and the bezel and re-secured. Yes, that is a plastic water bottle converted to an Airstream anti-corrosion “washer.” Time will tell if it works.
