Huh??? The Zolatone 20 series found on Zolatone AIM (http://www.zolatoneaim.com/) is the old stuff. The color combos have changed over the years. The Polomyx is unrelated to the stuff Airstream used and results in a totally different effect. It's an architectural finish (think hospital interior walls). You can even roll it...
