Road Runner-Duct work painted with Dryfall Paint

Over at Road Runner last week..the duct work was being painted with Dryfall Paint.Dryfall paint is a type of paint used paint for fast refinishing of ceilings by airless spray application. Designed so that under normal conditions of application the overspray does not stick but falls to the floor as dry dust which may be swept up without damaging the surface (the surface must be dry). Dryfall paint makes it possible to paint ceiling beams, girders, trusses, corrugated metal, concrete, wood, etc without the costly operation of covering. It also contains flash rust inhibitor to minimize rusting when applied over ferrous metals.
