I find it interesting that when I asked Airstream for information about the clearcoat they simply did not seem to know exactly what it is. Apparently it is applied by an independent contractor between Alcoa's factory and when it gets to Airstream. I did find the name of the product once by searching but in the end I lost interest in my search and forget what it was...
I do remember that it is an acrylic finish of some kind though.
If you look at a late model Airstream, you can see that the end caps have a dull finish compared to the rest of the panels, this is a result of the stretching of the finish when the panel is in the die being pressed into shape.
I have inquired about polishing our Airstream and the people I spoke to say that the finish is extremely difficult to remove.
That is all I know....
