The most experienced and dexterous brush hands find it extremely difficult to brush shellac uniformlyand without laps. It is undoubtedly in the applica-tion of shellac that the Aeron System shows togreatest advantage. The aeroned coat of shellac isperfectly smooth and uniform and, comparativelyspeaking, requires no sanding; the gum is usually cut2^2 pounds to the gallon of alcohol. It is with surprising ease that white undercoatsand enamels are handled with the Aeron. In brush-ing white finishes several coats are necessary to prop-erly cover the job, while in aeroning—owing to uni-.

As further evidence of the superiority of the AeronSystem it might be pointed out that one coat of whiteprimer when aeroned will completely cover a piece ofwork as well or better than two coats brushed. Highlypresentable product is turned out in two and threecoats satin finish with this System; highest graderubbed work is done in four coats. There are factories which are successful in theaeroning of stains and fillers. However this process isnot so applicable to these materials as to the othersmentioned. As might be expected the saving of time is more orless regulated by the materials applied, the class ofgoods finished, and the factory process of handling thegoods. It is safe to say, however, that one manoperating the Aeron can do a given amount of work infrom one-half to one-tenth of the time
