I am not sure why the lacquer dullcoat works so well over enamels, but it does. In fact, it seems to work better than their enamel clearcoats. I did not like their enamel clearcoats- they took a long time to dry, and did not give as flat a finish. I usually use their spray cans, but have used the bottle versions with both brush and airbrush, and it works as well as the spray can versions. I sometimes use the bottle of gloss clear when weathering to add a streak, with a small brush, to represent a wet area.
