Hey- you can try your idea easily, and if you don't like it, paint out the zolatone. I'd say, as an architect, that two finishes like that in a small space, like an Airstream, will draw attention to the difference between the two finishes. You'd rather have something else be the focal point of your trailer's interior... I'm curious to see how you like it, I just decided to paint mine today. Some of the Zolatone colors were better than others. Mine is beige and looks dirty.
Wherever you go, there you are
