Correct. In my case I do not use sauce. I use defatted drippings, a hint of butter, and usually an emulsifier of some sort, often a touch of Dijon. I use the paint on the slices, on the sides. (Sauce I serve on the side.) It adds and also helps hold in moisture. Brisket, as many know, once sliced, can take on a dry appearance even if the meat isn't dry in reality.
