I think it's stainless. It's on the ceiling of the Interstate, which with the walls all appear to be stainless.

From reading the thread link Al-K4GLU posted, looks like we should treat with WD40, scrub clean and maybe apply a clear coat of some sort before adding a gasket. The corrosion had just started to creep out from under the fixture, which is why we noticed it.

If it's aluminum, should we do something different?

Thanks, all.
